Athletic Activity Monitoring Device with Energy Capture

摘要

Aspects relate to an energy harvesting device adapted for use by an athlete while exercising. The device may utilize a mass of phase-change material to store heat energy, the stored heat energy subsequently converted into electrical energy by one or more thermoelectric generator modules. The energy harvesting device may be integrated into an item of clothing, and such that the mass of phase change material may store heat energy as the item of clothing is laundered.

主权项

1. An energy harvesting device, comprising:
an insulated container, comprising:
a thermoelectric generator module positioned within an internal cavity, the thermoelectric generator sandwiched between an outer heat exchanger and an inner heat exchanger, the insulated container having a primary axis of conduction through the inner heat exchanger, the thermoelectric generator, and the outer heat exchanger; anda processor, wherein the processor is powered by the thermoelectric generator, wherein the processor is configured to monitor a voltage output from the thermoelectric generator, and wherein the output voltage is proportional to a thermal gradient between the outer and inner heat exchangers such that the thermoelectric generator functions as a heat flux sensor.
