Thermal Energy Harvesting Enables Wireless Sensor Deployment

Marlow Industries (Dallas, TX) has introduced the EverGen series of thermoelectric-based energy harvesting devices, offering a zero-maintenance power solution for wireless sensor applications. EverGen thermal energy harvesters power wireless sensors without a battery, reducing replacement costs.

By converting small degrees of temperature difference into milliwatts of electrical power, the new line of thermoelectric energy harvesting solutions can power wireless sensors for the lifetime of the application. The EverGen offers a solid-state, reliable energy source for sensors, actuators, valve solenoids, and other small devices by recycling wasted heat.

With new building codes requiring sophisticated lighting, heating, ventilation, and air-conditioning systems, smart designs are key to moderating usage. By integrating Marlow’s thermoelectric energy harvesters, builders will have a cost-effective alternative that will relieve resources spent powering these devices.

Three energy harvesting solutions are available:

  • EverGen Liquid-to-Air: harvests the thermal energy between a higher temperature fluid stream and ambient air via natural convection for conversion to electrical power.
  • EverGen Liquid-to-Liquid: harvests the thermal energy between a higher temperature fluid stream and lower temperature fluid stream for conversion to electrical power.
  • EverGen Solid-to-Air: harvests the thermal energy between a higher temperature solid surface and ambient air via natural convection for conversion to electrical power.
