  • Electric field sensing devices and systems and method of making the same
    Patent number: 11385376
    Abstract: An electric field sensing device. The device includes a substrate, a sensing medium capable of experiencing a change in its electrical resistivity in response to an electric field, and electrodes for use in measuring the change. A method of making an electric field sensing device. The method includes depositing on a substrate a sensing medium capable of experiencing a change in its electrical resistivity in response to an electric field emitted by an object; and placing electrodes for use in measuring the change. An electric field sensing system. The system contains a plurality electric field sensing devices, an arrangement of the plurality sensing devices in a way to detect spatial variation of electric field emitted by objects in an environment; a computer system capable of monitoring the sensing devices, and detecting and comparing differences between the electrical fields sensed by individual devices.

  • Solid-state electrolytes and batteries made therefrom, and methods of making solid-state electrolytes
    Patent number: 11201350
    Abstract: Method of making solid-state electrolyte with composition formula Li7-xLa3Zr2-xBixO12. The method includes making a polymerized complex of the metal-ions of the composition formula, and making an agglomerate therefrom to be calcined and sintered to produce the solid-state electrolyte. A solid-state electrolyte with the composition formula Li7-xLa3Zr2-xBixO12 with superior ionic conductivity by choice of the value of x and processing conditions. A battery employing a solid-state electrolyte of superior ionic conductivity with the composition formula Li7-xLa3Zr2-xBixO12.
