One approach is the use of thermoelectric energ y harvesting\, where energy is extracted from thermal gradients using a so lid-state thermoelectric generator (TEG). Even centimeter-scale TEGs can p rovide microwatts of power from small temperature gradients\, such as body heat\, but they present a number of challenges in terms of low-voltage\, highly-efficient energy conversion at the output.\n\nIn this talk\, I will present recent work in low-voltage energy harvesting applied to wearable devices\, including some of our own low-level improvements in DC-DC conver ters and complete thermoelectric energy harvesting solutions – including true battery-less\, wearable bioelectronic sensors powered by body heat. I will also present a number of ultra-low-power (ULP) sensor readout inter face circuit approaches that enable ULP (<10µW) read-out for resistive-\, voltage-\, and current-domain sensors\, such as temperature\, pH\, and el ectrochemical reactions. Together\, thermoelectric energy harvesting combi ned with ULP sensors and read-out ICs are a promising avenue for powering wearable devices using body-heat energy harvesting.\n\nBio:\n\nMatthew Joh nston received the B.S. degree in electrical engineering from the Californ ia Institute of Technology in 2005\, and the M.S. and Ph.D. degrees in ele ctrical engineering from Columbia University in 2006 and 2012.
