Thermobility™ from Laird Thermal Systems is a new energy-harvesting technology that uses heat as a source of electricity for ultra-low-power wireless applications. The power generator uses innovative solid-state thin-film thermoelectric technology to convert waste heat into usable output DC voltage.

The WPG-1 is a self-contained thin-film thermoelectric power generator that harvests waste heat and converts it to usable output DC power. Due to its compact size, output power generation and ability to regulate voltage this device is suitable for use in applications to power wireless sensors and wireless sensor networks.

One WPG-1 can produce up to 1.5 mW of usable output power and can handle a wide range of load resistances. An ultra-low-voltage step-up converter is incorporated to provide usable output power at low temperature differentials, < 20°K. The output power can be regulated to accommodate three voltage set points: 3.3 V, 4.1 V or 5.0 V. Custom design services are available to accommodate alternate heat absorption and heat dissipation mechanisms or output power requirements, however MOQ applies.

Laird Thermal Systems' Thermal Wizard helps users find the best thermal solution based on their requirements. Users can input their Qc requirements or they can determine their Qc values with Laird’s calculators to quickly view the optimum thermal management solution.
