We present the development, fabrication and in vivo testing of a minimally invasive microelectrode array intended for high resolution multichannel recordings of electromyographic (EMG) signals. Parylene C was chosen as the structural substrate for its mechanical, electrical and physical properties. In particular, the device is extremely flexible. This provides a highly conformal coverage of the...

High-density electrocortical (ECoG) microelectrode arrays are promising signal-acquisition platforms for brain-computer interfaces envisioned, e.g., as high-performance communication solutions for paralyzed persons. We propose a multi-channel microelectrode array capable of recording ECoG field potentials with high spatial resolution. The proposed array is of a 150 mm2 total recording area; it ...

This paper describes the results of a study of a few design parameters influencing the performance of sensor arrays constructed from nanostructured thin films and interdigitated microelectrodes (IMEs). The nanostructured thin films on the IME devices were prepared from nonanedithiol (NDT) and mercaptoundecanoic acid (MUA) linked assemblies of 2-nm sized gold nanoparticles. The sensor array data...

Microelectrode array of the Cochlear Implants (CI’s) is an important component of the device which performs a key function in restoring the hearing process to the deaf patients. CI’s are available with different variants in the market with different design of the Electrode array. Due to the importance of Electrode array in CI it’s also been researched looking for ways to microfabricate in diffe...

A sub-dural surface microelectrode array designed to detect micro-field evoked potentials has been developed. The device is comprised of an array of 350-microm square gold contacts, with bidirectional spacing of 150 microm, contained within a polyimide Kapton material. Cytotoxicity testing suggests that the device is suitable for use with animal and human patients. Implementation of the device ...

Ultrahigh-throughput denaturing electrophoresis (>5000 channels) can enable rapid, low-cost mutation scans of human genomes. One design challenge for such instruments is successfully interfacing to the capillary channel array ends for loading and independently collecting DNA while enabling electrophoresis, permitting DNA detection, and preventing evaporation. A micro-well array based on tapered...

This paper reports on an active 16 x 16, low-noise, low-power, multi-electrode array (MEA) neural sensor chip designed in IBM BiCMOS 8HP 0.13μm process with a total gain of 60 dB per input, a 20 kHz sample rate, an input-referred noise of 5.3 Vrms over 10 Hz to 10 kHz and a total power dissipation of 15.8 mW, or 61.7 W per channel. A C4 microelectrode is attached to the input of each amplifier ...
