Describes the design, fabrication, and output capabilities of a microminiature electrical stimulator that can be injected in or near nerves and muscles and used successfully for chronic stimulation in hindlimb muscles of cats.Abstract:
Describes the design, fabrication, and output capabilities of a microminiature electrical stimulator that can be injected in or near nerves and muscles. Each single channel microstimulator consists of a cylindrical glass capsule with hermetically sealed electrodes in either end (2-mm diameter/spl times/13-mm overall length). Power and digital control data can be transmitted to multiple implants (256 unique addresses) via a 2-MHz RF field created by an external AM oscillator and inductive coil. In vitro testing demonstrated accurate control of output pulsewidth (3-258 /spl mu/s in 1-/spl mu/s steps) and current (0-30 mA in two linear ranges of 16 steps each, up to 8.5 V available compliance voltage). Microstimulators were used successfully for chronic stimulation in hindlimb muscles of cats. Design and fabrication issues affecting yield and reliability of the packaging and electronics are discussed.read more

New developments for high performance implantable stimulators: first 3 Mbps up to 4.46 Mbps demodulator chip through a wireless transcutaneous link
TL;DR: In this paper, a new telemetry system has been developed in order to fit with the common characteristics of future high performance radio-powered implantable stimulators which are requiring as high as possible data bit rate to control higher number of electrodes and/or accurate definition in the stimulus waveforms with enough power transfer.
On structural recognition with logic and discrete analysis
Levon Aslanyan,Hasmik Sahakyan +1 more
TL;DR: The paper addresses issues of special style structuring of learning set in pattern recognition area by treating logic separation hypotheses over the multi value features area, which structures the learning set and tries to recover more valuable relations for better recognition.

TL;DR: In this paper, a pulsed electric field was used to induce electroporation or electrofusion for renal neuromodulation, which may reduce expansion of an acute myocardial infarction, reduce or prevent the onset of morphological changes that are affiliated with congestive heart failure, and/or be efficacious in the treatment of end stage renal disease.
