Micropelt creates innovative solid state thin film Peltier cooler and thermogenerator devices that build on a scalable semiconductor platform technology. Micropelt products provide extreme power for cooling, cycling, and thermal management on a mm² scale as well as thermal energy harvesting and perpetual power supplies for self-sustained electronic devices. Micropelt solid state thin film devices target the chip spot cooling, energy harvesting, fiber optics, HVAC, and biomedical markets.
Micropelt TE-CORE RF ThermoHarvesting Wireless Sensor System is a complete thermo-powered, self-sufficient wireless sensor node system (WSN). It is based on an energy harvesting module with a power management function, which converts locally available waste heat thermoelectrically to indefinite free electric energy. A wireless sensor module is connected to the TE-CORE RF and is equipped with Texas Instruments (TI) ultra-low power technology (CC2530). A temperature difference of as little as 10ºC between a hot surface and ambient air is enough for the TE-CORE RF to make a temperature measurement and a radio transmission every two seconds. Information about the thermal profile of the heat source, the generated output power, the thermal generator output voltage, the energy storage voltage and battery equivalent are displayed via a USB receiver and PC application software.
The Micropelt TE-CORE ThermoHarvesting Module converts locally available waste heat thermoelectrically to indefinite free electric energy - as long as the heat flows through the thermogenerator (TEG). The integral power conversion and management circuit steps up the gradient-analog' output voltage of the TEG and outputs a fixed voltage (2.4 V by default). The Micropelt TE-CORE ThermoHarvesting Module's harvested energy is being buffered in an extendable capacitor and controlled by a configurable hysteresis.
