1 Harrison, Reid R.;Normann, Richard A.Design and testing of an integrated circuit for multi-electrode neural recordingWe have developed a single-chip neural recording system with wireless power delivery and telemetry. The 0.5-μm CMOS IC is designed to be bonded to the back of a 100-channel Utah Electrode Array. A pad near each amplifier allows connection of the chip to the MEMS electrode array. The complete Integr...recording; Neural recording; Utah Electrode Array; Multielectrode arrays (MEA); Telemetry; Spike detectors; Wireless2007-01
2 Harrison, Reid R.HermesC: low-power wireless neural recording system for freely moving primatesNeural prosthetic systems have the potential to restore lost functionality to amputees or patients suffering from neurological injury or disease. Current systems have primarily been designed for immobile patients, such as tetraplegics functioning in a rather static, carefully tailored environment....Brain-machine interface; Low power; Neural prosthetics; Telemetry; Wireless; Neural recording; HermesC2009-08
3 Harrison, Reid R.Influence of system integration and packaging for a wireless neural interface on its wireless powering performanceIn an integrated wireless neural interface based on the Utah electrode array, the implanted electronics is supplied with power through inductive coupling between two coils. This inductive power link would be affected by conductive and dielectric media surrounding the implant coil. In this study, th...Implant coil; Wireless; Integrated Neural Interface; INI3; Utah Electrode Array2008-01-01
4 Harrison, Reid R.;Normann, Richard A.Low-power integrated circuit for a wireless 100-electrode neural recording systemIn the past decade, neuroscientists and clinicians have begun to use implantable MEMS multielectrode arrays (e.g., [1]) to observe the simultaneous activity of many neurons in the brain. By observing the action potentials, or "spikes," of many neurons in a localized region of the brain it is possibl...Electrode; Multielectrode arrays (MEA); Neural recording; Low-power circuits; Wireless2006-01-01
5 Harrison, Reid R.Polymer based thin film coils as a power module of wireless neural interfacesFor the conventional Utah Electrode Array (UEA) to be able to function without transcutaneous wire connections, a kind of power source is needed in an integrated form with the UEA. To develop such wireless neural interfaces, inductive coupling between two coils was used to deliver power to the integ...Wireless; Neural interfaces; Thin film coils; Utah Electrode Array2006
6 Harrison, Reid R.Wireless integrated circuit for 100-channel neural stimulationWe present the design of an integrated circuit for wireless neural stimulation, along with bench-top and in-vivo experimental results. The chip has the ability to drive 100 individual stimulation electrodes with constant-current pulses of varying amplitude, duration, interphasic delay, and repetiti...Wireless; Integrated Neural Interface; Neural recording; Telemetry2008-11
7 Harrison, Reid R.Wireless neural interface for chronic recordingA primary goal of the Integrated Neural Interface Project (INIP) is to develop a wireless, implantable device capable of recording neural activity from 100 micromachined electrodes. The heart of this recording system is a low-power integrated circuit that amplifies 100 weak neural signals, detect...Integrated Neural Interface; Wireless; Neural recording; Telemetry2008-11
8 Harrison, Reid R.Wireless neural signal acquisition with single low-power integrated circuitWe present experimental results from an integrated circuit designed for wireless neural recording applications. The chip, which was fabricated in a 0.6-μm 2P3M BiCMOS process, contains 100 amplifiers and a 10-bit ADC and 902-928 MHz FSK transmitter. Neural signals from one amplifier are sampled by...Low-power; Wireless; Neural recording; Integrated Neural Interface; INI3; Utah Electrode Array2008-05
