Stimulator Design of Retinal Prosthesis
This study focuses on the design of electrical stimulator for retinal prosthesis. The stimulator must be designed such that the occurrence of electrolysis or any irreversible process in the electrodes and flexible lead is prevented in order to achieve safe stimulation over long periods using the large number of electrodes. Some types of biphasic current pulse circuits, charge balance circuits, ...
متن کاملMicro-stimulator Design for Retinal Prostheses
SINGH, PRAVEEN RAJAN. Micro-stimulator design for retinal prostheses. (under the direction of Dr. Wentai Liu.) The purpose of this research is to design an integrated circuit (IC) to stimulate retina. The IC is able to generate electrical stimulus specified by medical researchers. The IC is optimize for power and area, as it has to be implanted inside the eye. Specified area goal is to provide ...
متن کاملRetinal Stimulation on Rabbit Using Complementary Metal Oxide Semiconductor Based Multichip Flexible Stimulator toward Retinal Prosthesis
The technological improvement helps many medical areas. The audiometric exams involving the auditory evoked potentials can make better diagnoses of auditory disorders. This paper proposes the development of a stimulator based on Digital Signal Processor. This stimulator is the first step of an auditory evoked potential system based on the ADSP-BF533 EZ KIT LITE (Analog Devices Company – USA). T...
متن کاملOptoelectronic retinal prosthesis: system design and performance.
The design of high-resolution retinal prostheses presents many unique engineering and biological challenges. Ever smaller electrodes must inject enough charge to stimulate nerve cells, within electrochemically safe voltage limits. Stimulation sites should be placed within an electrode diameter from the target cells to prevent 'blurring' and minimize current. Signals must be delivered wirelessly...
متن کاملAn Implantable Retinal Stimulator Design for Long-term Animal Experiments
an implantable stimulator, which provides continuous electrical stimulation and an external component, which provides preset stimulation parameters and power to the implanted stimulator via a paired RF (radio frequency) coil. A rechargeable internal battery and a parameter memory part were introduced to the implantable stimulator to avoid use of the external component during the stimulation cyc...
