1 Harrison, Reid R.HermesC: RF wireless low-power neural recording for freely behaving primatesNeural prosthetics for motor systems is a rapidly growing field with the potential to provide treatment for amputees or patients suffering from neurological injury and disease. To determine whether a physically active patient such as an amputee can take advantage of these systems, we seek to devel...HermesC; RF wireless; Low-power; Neural recording; Neural prosthetics; Integrated Neural Interface; Macaques2008-05
2 Harrison, Reid R.Low-power integrated circuit for adaptive detection of action potentials in noisy signalsThe advent of microelectrode arrays allowing for the simultaneous recording of 100 or more neurons is leading to significant advances in science and medicine. However, the amount of data generated by these arrays presents a technical challenge if these systems are ever to be fully implanted for n...Low-power; Spike detection; Neural recording; Low-power circuit design; Neuroprosthesis; CMOS2003-01-01
3 Harrison, Reid R.Single-chip CMOS visual orientation sensorWe present a single-chip, low-power vision sensor capable of measuring local edge orientation across a wide field of view. The sensor was fabricated in a 0.5-µm CMOS process. Quadratic spatial filters were implemented using differential pairs and an "antibump" circuit to give a current-mode out...Low-power; Vision sensor; CMOS2004-01-01
4 Harrison, Reid R.Wireless integrated circuit for 100-channel charge-balanced neural stimulationThe authors present the design of an integrated circuit for wireless neural stimulation, along with benchtop 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 ...Wireless integrated circuit; Low-power2009-12
5 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
