Vanderbilt researchers have discovered a method ofmonitoring the placement of electrodes in cochlearimplants (CIs) through the use of electrical impedancemeasurements. This technology offers real-timefeedback on electrode positioning, which can beused to more accurately place electrodes duringinitial implantation, or better program the implantsafter they have been placed. These enhancementscombine to give increased hearing quality to bothnew and existing CI patients.

The A.R.M.A. Laboratory of Vanderbilt University has developed a novel continuum robot design enabling multi-scale motion at the macro and micro scale. The unique design allows miniaturization with minimal added cost thereby potentially giving rise to a new generation of surgical robots capable of both macro-motion for surgical intervention and micro-scale motion for cellular-level imaging or intervention. Micro-motion is achieved through a unique method for altering the equilibrium pose of the robot via material re-distribution throughout the length of the robot. This process ushers in a new class of surgical robotics termed continuum robots with equilibrium modulation (CREM).

An assistive device for individuals with upper extremity neuromuscular deficit has been developed by researchers at Vanderbilt. This device is specifically designed for patients having hemiplegia following stroke, incomplete spinal cord injury, multiple sclerosis, and other disabilities and conditions, who may have severe muscle weakness or inability to fully control an upper limb. In order to facilitate use of the upper limb, the patient can wear the device as a substitute for or a supplement to the patient's volitional movement.
