The implant consists of 60 electrodes, each 200 microns in diameter. [ 4 ] [ 6 ] The resolution of the 6 dot by 10 dot rectangular grid image (produced by the 6 by 10 array of 60 electrode, of which 55 are enabled ) in a person's vision is very low relative to normal visual acuity.
Chronic brain-computer interfaces come in two varieties, stimulating and recording. Applications for stimulating interfaces include sensory prosthetics (cochlear implants), for example, are the most successful variety of sensory prosthetics) and deep brain stimulation therapies, while recording interfaces can be used for research applications and to record the activity of speech or motor ...
A typical electrode gel consists of a mixture of water, a thickener such as polyvinyl alcohol or carboxymethyl cellulose, and an electrolyte to increase conductivity. [1] [2] Some electrode gels have been shown to pose a potential fire risk when high-energy pulses are used, as for example when defibrillators are used. [3]
Orthopedic implant example seen with X-ray. An orthopedic implant is a medical device manufactured to replace a missing joint or bone, or to support a damaged bone.
