Wireless Implantable Drug Delivery Device Based On Shape Memory Alloy Microactuator

RESEARCH PROJECT

Title        :  Wireless Implantable Drug Delivery Device Based On Shape Memory Alloy Microactuator

Abstract :


            This project propose a novel out-of-plane microactuator based on a bulk-micromachined SMA coil with a built-in heater that is controlled wirelessly using RF magnetic fields. The out-of-plane SMA coil will be microfabricated through a planar process and self-assembled by locally controlled bending of the coil structure. The SMA coil acts as both a resonant heater circuit, which receives RF power wirelessly for heat generation, and a vertical actuator structure. This monolithic approach is aimed to reduce the overall size of the actuator and heat loss associated with the hybrid device, while eliminating the need for bonding and assembly processes for SMA integration. Direct wireless heating of the SMA coil is expected to improve temporal response and reduce the temperature gradient of the actuator.
