  • Circuit and method to improve energy harvesting efficiency in piezoelectric harvesters
    Patent number: 8026650
    Abstract: An energy harvester circuit is provided. The energy harvester circuit includes a harvesting module for extracting energy from an ambient source. A bias flip module manages the manner in which voltage across the harvesting module transitions when input current from the harvesting module changes direction so as to allow a majority of the charge available from the harvesting module to be extracted. A voltage transitioning module is shared amongst one or more DC-DC converters for efficient energy management.
