  • Wireless microactuators and control methods
    Patent number: 9370628
    Abstract: Embodiments of the present technology include a micromachined implantable drug delivery devices, grippers, and syringes that are wirelessly powered and controlled by frequency tuning of external radiofrequency (RF) magnetic fields. An illustrative device can be designed and constructed with passive circuitry and microvalves that operate without batteries, e.g., through thermal actuation of hydrogel microvalves and/or shape-memory alloy members. The frequency selectivity in the device control provides not only a path to achieving reliable and safe operation of drug delivery but also potential applications for selective delivery of multiple drugs.
