Development of a Vibration-Powered Wireless Temperature Sensor and Accelerometer for Health Monitoring S. George RLW, Inc. 2029 Cato Avenue State College, PA 16801 434-975-2210 sgeorge@ Abstract—This paper describes and evaluates the continued vibration, airflow, light, RF, and human motion [5]. So far, development of a prototype vibration-powered, wireless a major impediment to more widespread implementation of sensor for use in Condition Based Maintenance (CBM) wireless, self-powered sensors has been a lack of sensors applications1,2. To reduce installation and maintenance that can scavenge enough energy to operate as well as their costs, the CBM industry is turning interest increasingly battery or wall-powered equivalents in non-laboratory toward wireless, self-powered sensors, but a major applications. impediment to more widespread implementation has been a lack of sensors that can scavenge enough energy to operate RLW, Inc. presented an evaluation of a prototype vibration- as well as their battery or wall-powered equivalents. The powered wireless sensor for health monitoring at the 2005 sensor described in this paper solves that problem by IEEE Aerospace Conference [6]. At the time, RLW had implementing
