Dry biopotential electrodes used for the measurement of low-amplitude biopotentials, e.g. of the electroencephalogram, typically rely on active signal amplification and filtering at the location of signal acquisition. However, the additional power required for signal processing prevents the usability in emerging zero-power wearables and body-area-networks. To enable active biopotential electrodes in zero-power applications, we present a miniaturized and integrated power supply based on thermal harvesting of human body heat. Using commercial components in a custom assembly, a minimum of 8 uW power can be continuously supplied to a load at 2V, satisfying the demand of an ultralow power biopotential front-end Show more
