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 recti...fied 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.
