Based upon the Seebeck effect, thermoelectric generators (TEGs) convert temperature differences across dissimilar materials into an electrical potential, or voltage.

When connected to a load, such as a wireless sensor, this voltage difference causes current flow and renewable power is delivered.

Historically, thermoelectric generators have been constructed with discrete pairs of brittle thermoelectric materials sandwiched between solid porcelain plates, resulting in a rigid and bulky package.

In sharp contrast, Perpetua’s innovative approach applies thin semiconductors onto a flexible substrate using cost-effective and scalable semiconductor manufacturing techniques. Such manufacturing techniques enable Perpetua to combine large numbers of thermocouples easily and reliably, resulting in modules with much higher voltages than conventional thermoelectrics.

Building on over a decade of applied research and development, key differentiating elements of Perpetua's thermoelectric technology include:
• Higher voltages, eliminating the need for boost electronics
• Ease of varying power to match customer requirements (cost-effective sizing)
• Much lighter weight than traditional materials
• Flexible film can accommodate multiple package shapes and sizes
• Cost-effective semiconductor manufacturing techniques that are highly scalable

Perpetua Flexible Thermoelectric Film can save companies 50% or more compared to current battery systems and allow more sensor data to be collected, providing significant competitive advantages for you, our customer.
