Abstract

This paper reports a highly sensitive angular accelerometer utilizing a piezoresistive cantilever and spiral liquid channels. The spiral structure increases the total inertial force of liquid due to angular acceleration, which leads to the sensitivity enhancement. The differential pressure between two spiral liquid channels was measured by a piezoresistive cantilever with the resolution of 0.01 Pa. The developed sensor with number of turns of the spiral with 25 achieved the sensitivity enhancement by 28.5 times, compared to the ring channel sensor.
