Abstract

We have developed a fully implantable 4-channel wireless muscle stimulator system with the ability to elicit precise and graded muscle movements for a hand grasping motion. The stimulator system consists of a WiFi enabled inductive powering and data transfer circuitry connected to a laptop, and a wireless implantable stimulator unit with biocompatible stainless steel electrodes. We shall demonstrate this stimulator package and its features through a dummy robotic rat limb. We will also show videos of the stimulator being used to activate the rodent hind limb muscles to kick a ball, and activate the forearm muscles of a non-human primate to elicit individual finger movement to play a virtual piano.
