“…The typical cuff electrode is comprised of a self-coiling, double-layer silicone cuff embedded with two to three platinum foil strips and is wrapped around the outer surface of the nerve, thus providing a direct interface for electrical stimulation (Fig. 3) [46,73,97,128,148,149]. The electrode can operate at low stimulus thresholds, thus reducing the likelihood of detrimental nerve damage.…”

“…Cuff electrodes have been used safely for years, and although one study in rabbits found that long-term use of cuff electrodes had damaged myelinated axons, these axons were able to regenerate [64]. Furthermore, impedance and stimulation thresholds of cuff electrodes are stable over time, maintaining functionality for over 12 years in peroneal nerve stimulation experiments in hemiplegic patients [4,149,155,158]. Peroneal nerve stimulation can also be accomplished via functional electrical stimulation (i.e., transcutaneous stimulation) of the peroneal nerve, which has been demonstrated to improve gait quality following stroke to the same degree as ankle foot orthotics [11,135,141].…”

The aim of this study is to discuss the state of the art with regard to established or promising bioelectric therapies meant to alter or control neurologic function. We present recent reports on bioelectric technologies that interface with the nervous system at three potential sites-(1) the end organ, (2) the peripheral nervous system, and (3) the central nervous system-while exploring practical and clinical considerations.

“…Nerve cuff electrodes are currently one of the most promising recording devices for chronic implantation in humans, with safe implantation being reported for as long as 15 years [14]. One of the simplest types of nerve cuffs is a split cylinder containing three equally spaced ring electrodes embedded in the wall, as shown in Fig.…”

“…This arrangement is termed the quasi-tripole [14], [15], which has been used in a number of experimental studies and FES applications. However, EMG rejection by the quasi-tripole relies on perfect symmetry in cuff geometry and tissue resistivity, which will only be an approximation, at least due to manufacturing tolerances.…”

Abstract-This paper discusses certain important issues involved in the design of a nerve signal preamplifier for implantable neuroprostheses. Since the electroneurogram signal measured from cuff electrodes is typically on the order of 1 V, a very low-noise interface is essential. We present the argument for the use of BiCMOS technology in this application and then describe the design and evaluation of a complete preamplifier fabricated in a 0.8-m double-metal double-poly process. The preamplifier has a nominal voltage gain of 100, a bandwidth of 15 kHz, and a measured equivalent input-referred noise voltage spectral density of 3.3 nV Hz at 1 kHz. The total input-referred rms noise voltage in a bandwidth 1 Hz-10 kHz is 290 nV, the power consumption is 1.3 mW from 2.5-V power supplies, and the active area is 0.3 mm 2 .

“…The main energy of human nerve signals lie in the frequency band 400 Hz < f sig < 4 kHz and has a typical maximum amplitude of ±10 µV [1]. A preamplifier which brings the nerve signal to ±100 mV has previously been implemented and is reported in [2].…”

This paper presents the design of a third order low-pass Σ∆ analogto-digital converter (ADC) employing a continuous-time (CT) loop filter. The loop filter is implemented using Gm − C integrators, where the transconductors are implemented using CMOS transistors only. System level as well as transistor level design issues for power efficiency is discussed. A prototype Σ∆ ADC intended for weak biological signals restricted to bandwidths below 4 kHz has been manufactured in a standard 0.35 µm CMOS technology. The ADC has a measured resolution of 10 bits and a dynamic range (DR) of 67 dB at a sampling rate of f s = 1.4 MHz, while drawing a bias current of 60 µA from a modest supply voltage of 1.8 V, thus consuming 108 µW of power.
