US Patent 11513246 Energy harvesting techniques for wireless geophones

A geophone, and method for distributing geophones around a seismic data source are described. The geophone includes a housing, a spike provided on a bottom surface of the housing, a sensor configured to sense seismic data; a processor configured to process the seismic data, a transceiver configured to transmit the processed seismic data and receive radio frequency (RF) signals wirelessly; and a power device. The power device is coupled to the sensor, the processor and the transceiver. The power device is configured to harvest energy from an environment where the geophone is located. The power device includes a solar cell provided on a top surface of the housing, a piezoelectric system provided on an edge of the housing adjacent to the top surface, and a thermoelectric generator provided on a bottom surface of the housing and a surface of the spike.
