Thermal energy for wireless sensor

  • 15-Mar-2010 06:03 EDT

Energy harvesting is used by ABB and Micropelt to replace the battery of a wireless sensor with a green, sustainable, maintenance-free power supply. An ABB WirelessHART temperature transmitter is equipped with a thermal energy harvesting unit containing two Micropelt MPG-D651 thermogenerators with a footprint of 6 mm2 each. A temperature gradient of 30°C between the sensed medium and ambient air is sufficient to cover the power demand of the mesh-networked wireless instrument. The technology can save hundreds of thousands of high-power batteries and, more importantly, enable the additional sensing points that will help produce energy more efficiently, optimize the use of process equipment, and shift to highly cost-efficient condition-based maintenance.
