The industry is still limited by challenging engineering problems. One significant problem is that energy harvesters such as thermoelectric generators (TEGs) typically produce a very low voltage. The available harvested energy is thus unusable without a power management integrated circuit (PMIC) to provide high efficiency voltage conversion at very low source voltages.
Matrix Industries has addressed this challenge with novel TEGs and PMICs. Specifically, their TEG technology can harvest energy from an environmental temperature difference of less than 1K. Their proprietary PMIC that was designed and manufactured in collaboration with Cactus Semiconductor, leverages a nano-power boost converter topology that provides micro-watt cold-start, impedance matching, and regulated output - at a low size and cost. Matrix has demonstrated the potential of combining these technologies by producing the first smart-watch to be powered solely by body heat.
This presentation introduces the prolific market that make these technologies attractive, elaborates on the electronics challenges faced during development, and provides a summary of the exciting results.
