    摘要： A micromachined multi-layered microbellows-style actuator capable of delivering larger deflections compared to a single layered flat membrane of comparable size. Anchor structures are disclosed that improve the strength of the microbellows membrane. A characterization apparatus is used to measure microbellows membrane performance. Thermopneumatic actuators having a resistive heater chip are also disclosed. The microbellows membrane is manufactured by alternating deposition of structural layers and sacrificial layers on a substrate. The structural layers can be made of silicon nitride and the sacrificial layers can be made of polysilicon. The substrate is etched from the back to form an opening exposing the sacrificial layers, and then the membrane is released by etching away the sacrificial layers.

    摘要： A surface micromachined micromagnetic actuator is provided with a flap capable of achieving large deflections above 100 microns using magnetic force as the actuating force. The flap is coupled by one or more beams to a substrate and is cantilevered over the substrate. A Permalloy layer or a magnetic coil is disposed on the flap such that when the flap is placed in a magnetic field, it can be caused to selectively interact and rotate out of the plane of the magnetic actuator. The cantilevered flap is released from the underlying substrate by etching out an underlying sacrificial layer disposed between the flap and the substrate. The etched out and now cantilevered flap is magnetically actuated to maintain it out of contact with the substrate while the just etched device is dried in order to obtain high release yields.

    摘要： Neuromodulation systems are described. An example neuromodulation system includes a controller wirelessly communicatively coupled to a host computer, a signal generator communicatively coupled to the controller, and a plurality of electrodes communicatively coupled to the signal generator. The controller, in conjunction with the signal generator and the at least one electrode are configured to deliver a stimulation to a mammal based on an instruction received from the host computer. The stimulation is configured to induce voluntary movement or restore function in the mammal.
