Flexible Thermoelectric Cooling
A large-area, solid-state cooling surface that bends to fit the body — delivering powerful direct cooling at low DC wattage, with no compressor, no refrigerant, and no added humidity.

Cooling that conforms
Conventional Peltier coolers are small and rigid, so they can't comfortably cover a large, curved area of the body. This device solves that with inter-component flexibility: an array of individual thermoelectric modules — each a conductive plate, a Peltier element, and a liquid-cooled heat sink — joined by an elastic material into one continuous, bendable body.
Protective spacers around each module absorb mechanical stress so the fragile elements and their bonds survive real-world use, like being leaned against as a backrest. Fluid is cycled through the heat sinks by either a pump-and-reservoir loop or a passive thermosiphon, carrying heat away efficiently so the contact surface stays cold.
Low-wattage & portable
Powerful cooling on a 12 V supply — runnable from a battery bank, solar panel, or a vehicle outlet, with less waste heat.
Dry & on-demand
No refrigerant, no prep time, and no added humidity. Operates instantly using room-temperature fluid.
Heats too
Reverse the polarity and the same surface warms — and can reclaim waste heat or pre-chill the reservoir.
Built into what you sit in
Chairs, sofas & beds
The flexible panel integrates directly into a backrest or seat, its smooth membrane forming part of the furniture surface. For sedentary work and home entertainment, it cools the person — not the whole room — targeting the back and hamstrings where blood flow is high, at a fraction of the energy and real-estate cost of air conditioning.
Vehicle seating
The membrane can serve as the contact surface of a vehicle seat, conforming to its curves. Running on the car's 12 V system, it cools occupants directly — and in some geographies and vehicle classes can supplement or replace cabin A/C, simplifying the engine bay and improving efficiency.
