Abstract
The MEMS accelerometer has a high cross sensitivity due to proof mass being eccentric. This paper gives results for a SU-8 z-axis accelerometer that uses 8-resistor Wheatstone-bridge to reduce the x-axis and y-axis cross sensitivity by 2 orders of magnitude compared to the conventional 4-resistor Wheatstone-bridge arrangement.
