Thermoelectric Energy Harvesting

From Technology to Systems

Micropelt thin film thermogenerators enable a wide spectrum of applications and solutions. They are the basis for self-sufficient sensors and actuators in wireless networks. Along the value chain, Micropelt provides a complete range of product offerings – from single thermogenerator chips to certified wireless sensor and actuator systems.

• Smart valves for commercial and domestic heating systems
• Wireless sensors for failure prevention in electrical distribution systems
• Industrial condition monitoring
• Low cost harvesting devices used in a wide range of battery-free applications

Micropelt Systems

Wireless thermostatic » radiator valves (iTRV) powered by a Micropelt thermogenerator enable single room controllers to operate heating radiators in residential and commercial » buildings. With such an enhanced energy-friendly heating control system the costs can be significantly reduced by up to 30 %. This smart valve is easy to install and a perfect fit for retro installations.

Switch gear sensor systems provide failure alert through constant monitoring of electrical distribution systems. Continuous temperature and current monitoring indicates overheating at its early stages, so the risk of sparking and burning contacts in a random peak load situation is largely decreased.
The Micropelt » qmNODE generates its power through » energy harvesting from the resistive heat of the monitored busbar and communicates its measurement data with gateways to monitoring systems. This is the only available retrofit, mount-and-forget sensor solution that can run unattended for its entire service life. It takes just a few seconds to mount it.

Micropelt Thermogenerators

Our solid state thin film » thermogenerator devices convert a temperature difference into electrical energy. Those self-sustained energy sources harvest thermal energy that’s otherwise lost to the environment. A temperature gradient of 2 degrees over the thermogenerator can activate a DC/DC booster and power your electronics. More output power can be delivered at higher gradients, for instance 1 mW at 10 degrees and 4 mW at 20 degrees. 1 mW represents a battery-equivalent of more than 12 coin cell batteries a year. The thermogenerators are built on a scalable semiconductor platform » technology.
