AB  - The existing instruments for aerodynamic pressure measurements are usually built around
an array of discrete pressure sensors, placed in the same housing together with a few discrete
temperature sensors. However, this approach is limiting, especially regarding miniaturization, sensor matching, and thermal coupling. In this work, we intend to overcome these limitations by proposing a novel MEMS multisensor chip, which has a monolithically integrated matrix of four piezoresistive MEMS pressure-sensing elements and two resistive temperature-sensing elements. After finishing the preliminary chip design, we performed computer simulations in order to assess its mechanical behavior when measured pressure is applied. Subsequently, the final chip design was completed, and the first batch was fabricated. The used technological processes included photolithography, thermal oxidation, diffusion, sputtering, micromachining (wet chemical etching), anodic bonding, and wafer dicing.

AB  - The use of a filter bank of IIR filters for the spectral decomposition and analysis of signals has been popular for many years. As such, a new filter-bank resonator-based structure, representing an extremely hardware-efficient structure, has received a good deal of attention. Recently, multiple-resonator (MR)-based and general cascaded-resonator (CR)-based filters have been proposed. In comparison to single-resonator-based analyzers, analyzers with a higher multiplicity of resonators in the cascade provide lower side lobes and a higher attenuation in stopbands. In previous works, it was shown that the CR-based filter bank with infinite impulse response (IIR) filters, which is numerically more efficient than one with finite impulse response (FIR) filters, is suitable for dynamic harmonic analysis. This paper uses the same approach to design complex digital filter banks. In the previous case, the optimization task referred to the frequency responses of harmonic filters. In this work, the harmonic filters of the mother filter bank are reshaped so that the frequency response of the sum (or difference, depending on the parity of the number of resonators in the cascade) of two adjacent harmonic filters is optimized. This way, an online adaptive filter base can be obtained. The bandwidth of the filters in the designed filter bank can be simply changed online by adding or omitting the output signals of the corresponding harmonics of the mother filter.

AB  - Self-powered sensors are gaining a lot of attention in recent years due to their possible
application in the Internet of Things, medical implants and wireless and wearable devices. Human
breath detection has applications in diagnostics, medical therapy and metabolism monitoring. One
possible approach for breath monitoring is detecting the humidity in exhaled air. Here, we present an
extremely sensitive, self-powered sensor for breath humidity monitoring. As a power source, the
sensor uses electromagnetic energy harvested from the environment. Even electromagnetic energy
harvested from the human body is enough for the operation of this sensor. The signal obtained using
the human body as a source was up to 100 mV with an estimated power of 1 nW. The relatively low
amount of energy that could be harvested in this way was producing a signal that was modulated by
an interdigitated capacitor made out of electrochemically activated aluminum. The signal obtained
in this way was rectified by a set of Schottky diodes and measured by a voltmeter. The sensor was
capable of following a variety of different respiration patterns during normal breathing, exercise
and rest, at the same time powered only by electromagnetic energy harvested from the human body.
Everything happened in the normal environment used for everyday work and life, without any
additional sources, and at a safe level of electromagnetic radiation.

AB  - Food packaging ensures safety and hygiene, while reducing food waste, therefore it is and ssential component of the food supply chain. A sustainable and biodegradable alternative to conventional food packaging is edible packaging which contributes to the reducing waste and the economic efficiency of packaging materials. The numerous biopolymeric materials could be used as source such as polysaccharides (starch, cellulose, chitosan) and proteins (gelatin, soy protein, whey). Exopolysaccharides (EPS) are fermentation-based biopolyrners, secreted outside the cell wall and synthesized by various microbial species including bacteria, fungi and blue-green algae. Microbial levan is fructose-based EPS and convenient due to its biocornpatibility, renewability, high molecular weight, low viscous nature, antioxidant and prebiotic effects. Levan used in this work was produced by the B. licheniformis NS032 strain and its hydrophobic derivatives were obtained using octenyl succinic anhydride (OSA). Degree of substitution (DS) for modified levans were 0.025 and 0.032 for LH22 and LH25 respectively. Three different film compositions were prepared: 
levan/LH22/LH26 with gelatin in proportions 1:1. Films were prepared by casting technique and evaporated at room temperature. Morphology of the obtained films were studied by ARV (Atomic force microscopy), AutoProbe CP-Research SPM (TM Microscopes-Broker) and mechanical properties were examined by Shimodzu E2-LX tensile tester. The samples had thickness of 150 trrrl. Based on morphological measurements, it can be concluded that use of levan derivatives change roughness of the levan/gelatin blend film. The best mechanical properties (tensile strength and elongation at break) were obtained with pure levan. Obtained films are composed from edible and biodegradable components and therefore are potentially applicable in food industry. Future investigation will be focused on optimization of levan/gelatin proportion and more extensive 
structural and mechanical properties of obtained films.

AB  - Merenje u nesinusoidalnim uslovima je u centru istraživanja i mnogo se napora ulaže da se pojam reaktivne snage star više od sedamdeset godina definiše na nov način. Postoji niz pristupa rešavanju problema definisanja snaga i/ili pokušaja koncipiranja merne instrumentacije za merenje snaga u sistemima naizmenične struje pod nesinusoidalnim uslovima. Jedini standard koji se odnosi na specifične zahteve za tačnost i odgovarajuće uslove testiranja u prisustvu harmonijskih izobličenja je IEEE Std. 1459-2010, koji ne daje definiciju reaktivne snage u nesinusoidalnim uslovima. Koncept ovog IEEE standarda je baziran na raz-dvajanju snage na fundamentalni i nefundamentalni deo. U literaturi su prisutne različite tehnike za imple-mentaciju standarda IEEE Std. 1459-2010. Ovaj standard je implementiran pomoću dva osnovna prilaza: (1) dvostepeni algoritam sa estimacijom harmonijskih spektara naponskog i strujnog signala u prvom koraku i računanjem nepoznatih komponenti snage u drugom koraku i (2) filterska implementacija kombinovana sa Clarke-Park transformacijom u slučaju trofaznog sistema. U radu je prikazana nova metoda za merenje električnih veličina definisanih standardom IEEE 1459-2010 koristeći drugi pristup. Ključni elementi su adaptivni pojasni i niskopropusni FIR filteri koji izdvajaju fundamentalnu i jednosmernu komponentu. U radu su korišćene tehnike oversemplinga i decimacionih filtera, čime se izbegavaju problemi vezani za osetljivost na zaokruživanje koeficijenata FIR kaskadnih filtera velikog reda, smanjuje obim numeričkih računanja i povećava tačnost merenja. Estimacija simetričnih komponenti vrši se pomoću matrice adaptivnih faznih korektora. U cilju procene performansi algoritma izvršene su računarske simulacije i dati njihovi rezultati.
AB  - In this paper, the design and implementation of a novel recursive method for the power measurement ac-cording to the IEEE Standard 1459-2010 have been described. The most important parts are adaptive band and low-pass FIR filters that extract fundamental and dc components, respectively. In addition, by using oversampling techniques and decimation filters, coefficient sensitivity problems of the large-order FIR comb cascade structure are overridden and the parameter estimation accuracy is improved. The symmetrical components are estimated through a transformation matrix of adaptive phase shifters. The effectiveness of the proposed techniques is demonstrated by simulation results.

AB  - Recently, a multiple-resonator structure was proposed as a robust and computationally efficient tool for harmonic analysis. Two trivial cases have been previously observed. The first case exhibits good out-of-band suppression and elimination of unwanted harmonics, but with a high latency. In the second case, a phase frequency response around the passband centre is zero-flat, that provides fast estimates. However, in this case, resonant peaks at the ends of the passband and high interharmonic gains cause large overshoots. In general, the basic algorithm performance requirements: selectivity and speed, are contradictory which makes it impossible to completely fulfil both of them. In this paper, the Constrained Linear Least-Squares (CLLS) optimization method is used to obtain a compromise solution. As a result, the resonant peaks in the passband are avoided and side lobes are mitigated, simultaneously minimizing the group delay in the middle of the passband. Performed simulations confirmed the effectiveness of the proposed algorithm.

Standard 60255-118-1:2018 by usage of a multiple-resonator (MR)-based approach for harmonic
analysis having been proposed recently. In previously published articles, it has been shown that a
trade-off between opposite requirements is possible by shifting a measurement time stamp along the
filter window. Positioning the time stamp in a proximity of the time window center assures flat-top
frequency responses. In this article, through simulation tests carried out under various conditions, it
is shown that requirements of the IEC/IEEE Standard 60255-118-1:2018 can be satisfied by the second
and third order MR structure for particular conditions of the time stamp location.

AB  - Several types of MEMS and thin-film based sensors have been developed at the Institute of Chemistry,
Technology and Metallurgy (ICTM), including piezoresistive pressure sensors, a multipurpose thermal sensor, and an
adsorption-based mercury vapor sensor. In this paper, we present the concept of a portable electronic instrument that
can be used with different combinations of pressure, thermal and/or mercury sensors. Such an instrument is highly
configurable, thus enabling various measurements to be performed in different applications, from industrial plants to
environmental monitoring. Since the mentioned sensors have different requirements in terms of sensor excitation, as
well as different ranges of their output signals, the design of the instrument is a demanding task. Additional design
requirements are related to the portability of the instrument, including the overall dimensions, power source and
consumption, and communication methods. One of the possible directions of further development is the design of a
rugged version of the instrument, intended for harsh environments.

AB  - Test of a sensor with four resistors structure on its sensitivity as a temperature probe is described. The chip is sensitive on a temperature difference between Si substrate and air and less sensitive on the temperature of the whole chip. The sensor consists out of four resistors realized as metal meanders on a silicon chip patterned in 150 nm thick gold layer whose lateral dimensions are 0.94 mm by 0.6 mm and the length 14.1 mm. Width of meander line is 0.02 mm with clearance 0.02 mm. The resistors form Wheatstone bridge configuration. Current through resistors was kept constant on 5 mA. Offset of the bridge on no temperature difference was 1.5 mV. In the case of temperature difference on the sensor surface, sensor output is changing with linear dependence. This has a potential for the use in temperature stabilization systems.

The mercury sensor has already been developed at ICTM‑CMT and its functionality was tested and documented. The sensor is capable of sensing mercury concentrations below 1000 ng/m3. It is also capable of continuous monitoring of mercury concentration in air thanks to the special algorithm developed at ICTM‑CMT. This work is a part of our new effort towards making a compact and portable device for monitoring of the mercury vapor concentration in air in both industrial and natural environments. Sensor platforms like this could have a significant role in environmental remediation in cases of industrial accidents caused by human errors, natural disasters or war.

AB  - This Letter proposes a modified method for the dynamic harmonic analysis of signals with non-stationary harmonics, which is based on the previously proposed multiple-resonator observer structure. An optimisation technique is applied to reshape frequency responses of the basic transfer functions. This method, by using a parallel structure with common feedback, is very robust and, in addition, allows a reduction of the computational burden. The proposed method has been investigated for up to 64 harmonics, using LabView software package, under different conditions, and confirmed to be valuable and efficient tool for signal components estimation.

AB  - In order to improve the efficiency of the pressure sensors characterization process at the Center of Microelectronic Technologies (CMT), a new measurement setup is developed that enables fully automatic characterization of multiple silicon piezoresistive MEMS pressure sensors. The whole experiment, including high-performance measurement of sensors output signals at several temperature and pressure values, and storage of the measured results in a computer file, requires only a minimum of operator action. The setup consists of both hardware and software modules. The hardware is partly based on equipment designed and built at CMT for this purpose, and the software is entirely developed at CMT. This paper is focused on the software aspects of the developed experimental setup. The main objective of the presented work is to make the small series production of industrial pressure transmitters at CMT more efficient. The results are also very useful for research and development of pressure sensors and instrumentation.

AB  - In this paper we present the concept of a compact intelligent industrial pressure transmitter developed at the Center of Microelectronic Technologies (CMT), and discuss some of the most important steps in its design process. First the constraints of the design are defined, and then the decisions are made in order to fulfill the design objectives in an optimal way, which is made possible by using the latest available technology. Especially important for this design are mixed signal circuits, and the focus is on the digital-to-analog circuitry that generates the transmitter's analog output signal. Several solutions are considered and compared, and the chosen one is further investigated, including the experimental characterization of the output current error across the operating temperature range. Apart from industrial transmitters, the results of the work can be significant for other kinds of electronic instrumentation.

AB  - In this paper, a modified and improved approach to the recently proposed multiple-resonator-based observer structure for harmonic estimation has been proposed. In the previous papers, two inherent particular cases have been considered. In the first case, estimation is performed in the point located in the middle of the observation interval, and exhibits good noises and unwanted harmonics attenuation but possesses a large response delay. In the second case, the estimation point is at the end of the observation window. In this case, the filters are able to form a zero-flat phase response about the operation frequency and hence able to provide instantaneous estimates, but with large overshoots caused by resonant frequencies at the edges of the pass band, and the high level of the sidelobs. In this paper, the estimation point is shifted along the observation interval reshaping frequency responses to tradeoff between those opposite requirements. The effectiveness of the proposed algorithm is shown through simulations.

abstract = "In this paper is shown importance of modular architecture in the sustainable development of enterprises. The application of modular design enables the development of the production program based on the results of its own development. At the illustrated example, the production of transmitters it was concluded that modular architecture enables the production of independent entities, provides the realization of products in inaccessible places, enables to precisely defined technical documentation of modules, enabling easy maintenance, repair and improvement. This paper describes an algorithm for material reuse which indicates the importance of the customer in a closed material flow. In this connection, PLC includes protection of the environment as a strategic decision in the sustainable development of enterprises., U ovom radu je prikazan značaj modularne arhitekture u održivom razvoju preduzeća. Primena modularnog dizajna omogućava razvijanje proizvodnog programa koji se bazira na rezultatima sopstvenog razvoja. Na primeru, proizvodnje transmitera konstatovano je da modularna arhitektura omogućava proizvodnju nezavisnih entiteta, omogućava realizaciju proizvoda na nepristupačnim mestima, realizuje module prema tačno definisanoj tehničkoj dokumentaciji, omogućava lako servisiranje, popravke i unapređenje. U radu je opisan algoritam za ponovnu upotrebu materijala koji ukazuje na značaj kupca u zatvorenom toku materijala. S tim u vezi, ŽCP uključuje zaštitu životne sredine kao stratešku odluku u održivom razvoju preduzeća.",
