  • Publication number: 20200054229
    Abstract: Neural interfaces with the peripheral nervous system have been developed to provide a direct communication pathway between peripheral nerves and prosthetic limbs. Described herein is a microchannel integrated neural network device and system which can control the reinnervated muscles and interpret neurological signals. The acquired bioelectrical signals can be used for the interpretation of mind and create a neural map.

  • Patent number: 7461882
    Abstract: Apparatus and processes are disclosed that provide a microfabricated microtool having a mechanically actuated manipulating mechanism. The microtool comprises a tweezer having flexible arms, and an actuating mechanism. A biological, electrical, or mechanical component is grasped, cut, sensed, or measured by the flexible arms. The actuating mechanism requires no electric power and is achieved by the reciprocating motion of a smooth, rigid microstructure applied against the flexible arms of the microtool. In certain implementations, actuator motion is controlled distally by a tethered cable. A process is also disclosed for producing a microtool, and in particular, by micropatterning. Photolithography may be used to form micro-molds that pattern the microtool or components of the microtool. In certain implementations, the tweezer and actuating mechanism are produced fully assembled. In other implementations, the tweezer and actuating mechanism are produced separately and assembled together.
