Design of a Low-Noise Preamplifier for Nerve Cuff Electrode Recording
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...
متن کاملFascicle Selective Recording with a Nerve Cuff Electrode
AB STRAC'T A multipolar split cuff electrode is used for fascicle selective recording of the electroneurogram (ENG) of the sciatic nerve of the rabbit. Several electrode configurations were evaluated with regarding to seleclivity: the peroneal and tibial nerves were stimulated alternately and the ENG was recorded at different sides of the sciatic nerve. The results for two electrode configurati...
متن کاملevaluation of a low‑cost and low‑noise active dry electrode for long‑term biopotential recording
wet ag/agcl electrodes, although very popular in clinical diagnosis, are not appropriate for expanding applications of wearable biopotential recording systems which are used repetitively and for a long time. here, the development of a low‑cost and low‑noise active dry electrode is presented. the performance of the new electrodes was assessed for recording electrocardiogram (ecg) and electroence...
متن کاملSelective Fascicular Recording of the Hypoglossal Nerve Using a Multi- Contact Nerve Cuff Electrode
The use of nerve cuff electrodes as p a r t of a closed loop functional electrical stimulation (FES) system has been demonstrated as a reliable alternative to artificial sensors (e.g., strain gauge). T o circumvent the need for multiple electrodes to record neural activity f rom different fascicles within a nerve, the flat interface nerve electrode (FINE) is presented as a potential approach to...
متن کاملMulti-electrode Nerve Cuff Recording – Model Analysis of the Effects of Finite Cuff Length
the effect of finite cuff length on the signals recorded by electrodes at different positions along the nerve was analysed in a model study. Relations were derived using a one-dimensional model. These were evaluated in a more realistic axially symmetric 3D model. This evaluation indicated that the cuff appeared shorter because of edge effects at the beginning and end of the cuff. The method for...
