In this paper we present the first fully passive (battery-free) wireless transmission of multiple digital audio channels and images via modulated backscatter. We leverage a previously reported single chip, passive transponder that can digitize and uplink up to 10 analog input channels sampled at a rate of 26.1 kHz. Given a base station transceiver operating at a frequency of 915 MHz and a transmit...
While interfaces to the brain were recently confined to science fiction, cochlear implants and deep brain stimulators are now becoming commonplace. This forum will cover circuit and material technology used to stimulate and record signals from the nervous system. Issues familiar to many circuit designers - low noise design, micropower design, partitioning between digital and analog circuits - will...
In 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, the influences of the integration of implant coil on silicon based IC/electrode, thin film parylene coating,...
The authors have developed a single-chip neural recording system with wireless power delivery and telemetry. The 0.5-mum 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 integrated neural interface receives power wirelessly through a 2.64-MHz inductive link. A clock,...
One requirement of a chronically implantable, wireless neural interface device is the integration of electronic circuitry with the microelectrode array. Since the electronic IC dissipates a certain amount of power, it will affect the temperature in the tissues surrounding the implant site. In this paper, the thermal influence of an integrated, 3-dimensional Utah electrode array, to be implanted in...
