A SONOS memory cell is formed from a standard polysilicon NMOS transistor with the addition of a small sliver of silicon nitride inserted inside the transistor's gate oxide. The sliver of nitride is non-conductive but contains a large number of charge trapping sites able to hold an electrostatic charge. The nitride layer is electrically isolated from the surrounding transistor, although charges stored on the nitride directly affect the conductivity of the underlying transistor channel. The oxide/nitride sandwich typically consists of a 2 nm thi ....etc

ARTIFICIAL SILICON RETINA (ASR
The ASR is a silicon chip 2 mm in diameter and 1/1000 inch in thickness. It contains approximately 3,500 microscopic solar cells called microphotodiodes, each having its own stimulating electrode. These microphotodiodes are designed to convert the light energy from images into thousands of tiny electrical impulses to stimulate the remaining functional cells of the retina in patients with AMD and RP types of conditions. ....etc

ABSTRACT:
Blindness is more feared by the public than any other ailment. Artificial vision for the blind was once the stuff of science fiction. But now, a limited form of artificial vision is a reality .Now we are at the beginning of the end of blindness with this type of technology. In an effort to illuminate the perpetually dark world of the blind, researchers are turning to technology. They are investigating several electron ....etc

artificial retina is developed for the disabled to people, so that they can retrieve their view. It was developed with the help of external camera (cameras) who worked as a stimulus from view of the brain through electrodes. The device has been used as a substitute for the cells in the retina of the eye. They have been formulated using large-scale integration third dimension, so that a person can receive the exact image of an object that is in front of them.

The artificial retinas function using thin-film transistors and capacitors. This dev ....etc

The AT89C52 microcontroller is the heart of the design. Ultrasonic waves are transmitted to the free space and when touched the obstacle is reflected. The reflected waves are received by the receiver. The demodulator is used to process the signal and gives the processed signal to the microcontroller. The microcontroller then actuates the relay connected to the APR9600 of the voice IC by which the blind person can get to know the obstacle. The microcontroller is provided with an oscillator frequency of 12 mhz, and a l ....etc

artificial retina using thin film transistor technology ppt

Abstract

We have evaluated an artificial retina using thin-film transistors driven by wireless power supply. It is found that the illumination profile can be correctly detected as the output voltage profile even if it is driven using unstable power source generated by inductive coupling, diode bridge, and Zener diodes. This means the feasibility to implant the artificial retina into human eyeballs. ....etc

A cheap guidance system based on AT89C52 microcontroller is developed for facilitating visually impaired people. Ultrasonic sensors are used to calculate distance of the obstacles around the blind person to guide the user towards the available path. Output is in the form of voice which the blind person can hear e.g., right, left etc. In its advance mode, the system will be able to recognize objects using image processing algorithms. Results are presented to show the validity and performance of the system.

This new visual prosthesis produces ....etc
