Programmable MEMS Shock and Vibration Sensors Simplify Industrial and Instrumentation System Monitoring. Programmable iSensor® ADIS16240 triple-axis shock and impact sensor is optimized for user configurability while detecting and storing critical events for subsequent analysis. With usable bandwidth up to 1.6 kHz, it consumes less than 1 mA in continuous sampling mode. Programmable iSensor® ADIS16220 digital vibration sensor lets designers automatically capture profiles of subtle vibration shifts in industrial applications that require wide-bandwidth (22 kHz) sensing ...

Abstract: This paper describes a self-test procedure for a micromachined silicon accelerometer realized using a commercially available microprocessor. The accelerometer is fabricated using a combination of thick-film printing and silicon micromachining. The self-test procedure must be performed at resonance and the microprocessor is used to identify the individual resonant frequency of each device and confirm the operation of the PZT elements. The microprocessor could also be used in the future to fully test and calibrate the device thereby ensuring correct and accurate operation.
