In the context of wireless sensors (WSs)
autonomous in energy, this paper presents a single macro-fiber
composite (MFC) piezoelectric transducer which is used for the
first time as a multifunctional device as both sensor and energy
harvester in a time-multiplexing manner. The MFC is used as
an energy harvester to charge up a storage capacitor. When
there is sufficient energy, the WS is powered up and the MFC
is used as a sensor. A circuit was implemented to harvest
energy from the MFC and use the MFC as a sensor.
Experiment validation shows that the MFC has an accuracy of
up to 97 % as sensor and the circuit harvests energy from the
MFC at its maximum power point with up to 98 % efficiency.
