MENG-ZHU MA has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Piezoelectric hair-like sensor, method for making same, and electronic device using same
    Patent number: 11545611
    Abstract: A very small piezoelectric sensor capable of being mass produced includes a core, a piezoelectric layer on a surface of the core; and a conductive layer on a surface of the piezoelectric layer away from the core. The core is flexible and threadlike, the core is a first electrode of the piezoelectric sensor, and the conductive layer is a second electrode of the piezoelectric sensor. An array of such sensors allows the “skin” of a robot for example to simulate the sensitivity of hair-covered human skin. A method for making the piezoelectric sensor and an electronic device using the piezoelectric sensor are also disclosed.
    Type: Grant
    Filed: July 5, 2019
    Date of Patent: January 3, 2023
    Assignees: Interface Technology (ChengDu) Co., Ltd., INTERFACE OPTOELECTRONICS (SHENZHEN) CO., LTD., GENERAL INTERFACE SOLUTION LIMITED

  • Touch feedback and sensing device
    Patent number: 11338325
    Abstract: A touch feedback and sensing device includes a circuit board, a piezoelectric ceramic actuator on the circuit board; and at least one strain sensor on the circuit board. The piezoelectric ceramic actuator includes a piezoelectric ceramic block, a cathode and an anode on the piezoelectric ceramic block. Different voltages are applied to the cathode and the anode to vibrate the piezoelectric ceramic block. The circuit board vibrates with vibration of the piezoelectric ceramic block. The at least one strain sensor is configured to detect and monitor vibration of the circuit board.
