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.
