Everactive Selects CAP-XX Supercaps for Batteryless Wireless Self-Powered Industrial Monitoring IoT Systems Share Article Energy harvested from indoor and outdoor solar and temperature differentials is stored in CAP-XX supercaps as a power reservoir for Everactive IoT sensors that generate power entirely from harvested energy Everactive Eversensors (green) in the company's Batteryless Machine Health Monitoring solution deployed on a motor powertrain. CAP-XX supercap stores harvested energy to power the IoT device. The Everactive industrial IoT sensor harvests energy from light and changes in temperature, then stores that energy in the CAP-XX supercap. Eliminating the battery and battery maintenance is a game changer for companies wanting to widely deploy IoT monitoring devices.
