Self-Powered Wearable Breath-Monitoring Sensor Enabled by Electromagnetic Harvesting Based on Nano-Structured Electrochemically Active Aluminum

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