Most applications for IoT require that the sensors employed in such applications be self-powered and perform both sensing and transmission of information at low power levels. Researchers working in this theme are engaged in developing full system-level solutions to applications such as machine health monitoring, acoustic energy harvesting for flight noise monitoring etc. The approach followed here is to co-design both the harvesters and the associated low-power circuits. Some of the challenges and innovative circuit-level solutions in this theme are: achieving low-voltage startup, impedance matching and frequency tuning for efficient broadband power extraction, providing regulated output voltage for the RF-circuits to transmit the information etc. The theme brings together novel devices, sensors and low-power electronics.
