Bio-Integration

The core temperature of the human body is approximately 37 degrees Celsius. The Quantum BioEngine exploits the temperature differential between the core and the cooler surface area.

This video shows the integration of quantum dots and heat engines into the Quantum BioEngine.

Prototype 1

In this prototype of the Quantum Heat Engine, the LEDs represent the two different quantum dot semiconducting layers. Quantum dots facilitate the movement of electrons through the each pair of layers. By using quantum resonant tunneling, electrons efficiently jump from low potential energy to high potential, like salmon jumping up a fish ladder.

Prototype 2

The integration of the Quantum BioEngine consists of a 100nm² quantum dot heat engine fabricated into a 1cm² array, which is embedded in a cool area subcutaneously. The central layer of the array is maintained at a high temperature through conduction to an artery. Overall efficiency of the engine is determined by the chemical potentials of the quantum dot layers. The temperature difference of only 1 °C will produce 0.1 watts.
