MATRIX Gemini Thermoelectric Generator

Our thermoelectric technology converts heat to electric power, the same technology used by NASA to power the Voyager Spacecraft and the Mars Rover. It is based on the Seebeck effect discovered in 1821. In the absence of an applied voltage gradient V, electric current, J, can still be generated if there is a temperature gradient, T. A thermoelectric material must have a low thermal conductivity and high electrical conductivity to function efficiently. These properties are not commonly found in nature.

In order to make a thermoelectric material efficient, one must use a semiconductor whose Fermi level is tuned correctly by doping. Too much doping, and the Seebeck coefficient decreases. Too little doping and the electrical conductivity decreases. In addition, the semiconductor should have some mechanism to scatter phonons frequently. MATRIX has developed a nano-structured semiconductor, the Gemini, that accomplishes these things.

MATRIX Mercury

A thermoelectric module is composed of many tiny semiconductor "legs" that when added together create a larger voltage than one individual leg alone. However, the voltage generated by body heat is on the order of 20 to 100mV, too small to operate electronics. A DC-DC boost converter is needed to boost this small voltage to 5V to run the electronics and charge a battery.  Current off-the-shelf boosters have terrible efficiency and large startup voltage. MATRIX has developed the world's most efficient booster with the lowest startup voltage on the market today. We call it the MATRIX Mercury. 

Together the MATRIX Gemini and Mercury outperform any combination of thermoelectric and boost converter by 3X. 

Matrix’s solar cell technology utilizes amorphous silicon that is superior to crystalline silicon when absorbing indirect and indoor light. The solar cell is laminated onto the display module for a seamless construction and optical clarity.
