Abstract

We present a super wide-measurement range load sensor with high-durability for multi-biosignal sensing in daily life. We employ quartz crystal resonator (QCR) load sensor with super wide range (from 6 × 10-5 to 30 [N]) for sensing of biosignal ranges from mN order (e.g. heartbeat) to 100 N order (e.g. body motion). Furthermore, we implement an outer case to make the sensor durable against unexpected loads in practical use. The outer case increase the durability of the sensor 88 times higher than the sensor without outer case. Finally we succeeded in simultaneous sensing of heartbeat (≈ 100 [mN]) and body motion (≈ 25 [N]) with identical sensor.
