NDEL General Research

The Neural Devices Engineering Laboratory is designing and developing novel medical technologies, in particular circuits for neural interfaces. We primarily design neural stimulation circuits and inductively-coupled wireless power and data telemetry systems. We also study electrode-tissue interface, as well as the process for inducing nerves to fire, in order to develop optimized, longer-lasting neural interfaces for neural stimulation and recording applications and neuroscience research.

The Retinal Prosthesis for the Blind

One of the projects we are working on is a retinal prosthesis in collaboration with the Boston Retinal Implant Project, a group Dr. Kelly has worked with since 1996. The retinal prosthesis restores useful sight to people blind with degenerative retinal diseases by stimulating healthy retinal ganglion nerves to create a pixelated image.

Preventing Residual Electrode Voltage

NDEL is developing stimulation circuits that resolve the problem of residual electrode voltage by using feedback to drive the electrode voltage to zero, completely preventing the residual voltage from occuring.

Wireless Power and Data Telemetry

NDEL is developing transmitter and receiver circuits, as well as inductively coupled systems, for the wireless transmission of power to medical devices and data to and from medical devices. We are developing methods to optimally design telemetry coils, feedback systems to ensure delivery of the correct amount of power, and improved switching power transmission circuits.

Next-Generation Electroencephalography

NDEL is working with faculty in Electrical and Computer Engineering on the development of circuits and algorithms for next-generation EEG with higher resolution, lower power, and greater portability.
