Latest Patents

Guocheng Liu holds a patent for a Cascade-type hybrid energy cell. This invention describes a cascade-type compact hybrid energy cell (CHEC) that is capable of individually and concurrently harvesting solar, strain, and thermal energies. The cell comprises an n-p homojunction nanowire (NW)-based piezoelectric nanogenerator and a nanocrystalline/amorphous-Si:H single junction cell. Under optical illumination of approximately 10 mW/cm² and mechanical vibration of 3 m/s at a frequency of 3 Hz, the output current and voltage from a single 1.0 cm-sized CHEC were found to be 280 µA and 3.0 V, respectively. This output is sufficient to drive low-power commercial electronics. Six such CHECs connected in series were found to generate enough electrical power to light emitting diodes or drive a wireless strain gauge sensor node.
