Vibration-Powered IoT Sensors with Ultra-Low Power RF Communication

Ridgetop Group is actively seeking innovative solutions to integrate a vibration-based energy harvesting system into an ultra-low power IoT sensor and gateway design. This advanced design will feature cellular, GPS, BLE, and WiFi connectivity as part of the Sentinel Motion product line. Sentinel Motion is an IoT-based sensor system designed to monitor mission-critical equipment by tracking a combination of temperature, linear, rotary, or vibrational forces. Originally developed in collaboration with NASA for helicopter gearbox systems, this technology has been successfully adapted for the railroad industry. Sentinel Motion provides railroad operators with a comprehensive toolbox to detect and monitor faults and anomalies in tracks, wheels, and bearings. The system includes a wireless network of RotoSense™ smart sensors, the Sentinel Gateway communications device, and the Sentinel MotionView software package for data acquisition, analysis, and sensor-gateway management.
