Abstract :
This paper presents a self-sufficient tire-mounted wireless sensor node, (i) with a bulk acoustic wave (BAW)-based FSK transceiver, (ii) designed for an energy scavenger based low volume and low weight power supply, and (iii) a 3D vertical chip stack for compact, low volume, and robust pressure, inertia, and temperature sensing.
