Abstract: Example systems described herein may include one or more sensor devices that may be powered by a power device. The power may be transmitted from the power device to the sensor devices through a waveguide (e.g. a body). In some examples, the power device may be implemented using a near-field communication device (e.g. a mobile phone configured for near-field communication (NFC)). Magnetic fields generated by near-field communication devices may be transduced into electric fields and applied to a waveguide (e.g. a body) for transmission to the sensor devices. The sensor devices may harvest power from the signals received from the waveguide (e.g. the body).
