How our products leverage the untapped potential of waste heat to power the next generation of IoT devices and renewable energy infrastructure.
Converting Temperature Difference into Voltage
Thermal energy harvesting is the process of converting a temperature difference into electrical energy via the Seebeck Effect using thermoelectric generators (TEGs).
This effect relies on properties of a special class of semiconductors known as thermoelectric materials. When thermal energy migrates through them from a hotter side to a colder side, they create an electric potential.
To operate, our products require a heat flow. Typically, this will be taken from a hot surface such as a hot water pipe, sent through the device and returned to the cold side, usually the surrounding air via a cooling fin or a cold-water return pipe. The amount of energy the product produces is dependent on both the maximum hot temperature and the temperature difference. A higher temperature will produce more energy.
TEGs are promising alternative power supply
According to an article published in March 2021 by the news magazine Manufacturing Global, 98% of businesses report that a single hour of interruption affects their productivity, costing them more than € 100,000 (Production downtime due to battery change). In addition, our own investigations at key players in the different industry segments revealed the following challenges related to the use of battery driven sensor systems:
