Juan Aceros

Dr. Aceros received the M.S. degree in Mechanical Engineering and the Ph.D. degree in Electrical Engineering from Northeastern University, Boston, MA. He is currently a Senior Research Associate at Brown University. His research interests are in the area of fabrication of implantable neuroengineering devices and topics related to micro/nano fabrication and MEMS. He is a member of the Materials Research Society (MRS), the America Society of Mechanical Engineers (ASME) and the Institute of Electrical and Electronic Engineers (IEEE). 

Dr. Aceros works on the fabrication and development of fully-implantable, wireless neural interface devices for recording and transmitting cortical signals from the brain. These devices use MEMS intracortical microelectrode arrays to sense broadband (0.1 Hz – 7.8 kHz) neural signals and transmit them to an external receiver where they are processed for neural control applications. They are currently employed to assist with advanced physical neuroscience research and to aid in clinical applications. The long term goal of this work is to improve the mobility and independence of individuals with neurologic disease or illness. This includes detection of epileptic seizures, and rehabilitation of individuals with limb loss, disease, or paralysis (e.g. neuroprosthetics). The creation of such complex faces considerable challenges including developing state of the art low-noise, low-power microelectronics as well as biocompatible sensor units, powering schemes, energy storage, dimensioning for placement in the subcutaneous spaces available in the head, telemetry, and reliable packaging processes and materials for long-term implant applications.
