An Optimal Design Methodology for Inductive
Power Link
“We have used the design methodology to implement a power link for a retinal
prosthesis using the proposed closed-loop control technique. The entire power link has
been experimentally demonstrated through a hybrid system that is capable of delivering
250 mW at 16 V using a supply voltage of less than 5 V from a distance of 7 mm with
an overall efficiency of 67%, which includes the power dissipated in the control
circuitry.” [230]
Biological–Machine Systems Integration:
Engineering the Neural Interface
“The World Health Organization (2002 figures) estimates that globally there are more
than 160 million visually impaired, of which some 40 million are blind (loss of
walkabout vision). While many causes of blindness are either preventable or treatable,
there are limited treatment options available for conditions such as glaucoma, agerelated
macular degeneration (AMD) or retinitis pigmentosa (RP). These three diseases
provide the bulk of the motivation to develop a visual prosthesis.” [24]
Specificity of Cone Connections in the Retina
and Colour Vision. Focus on "Specificity of
Cone Inputs to Macaque Retinal Ganglion
Cells"
“L- (long wavelength; peak absorption, 565nm), M- (medium wavelength; peak
absorption, 535nm), and S- (short wavelength; peak absorption, 440nm) cones onto a
retinal ganglion cell?” [50]
