HI AM SOUNDARYA I WOULD like to get details on seminar report on electronic skin.. my friend just said seminar report on electronic skin will be available here and now I am living at mangalore and I last studied in mount carmel college and now doing engineering in alvas engineering and technology .. I need help on seminar report please do share

Electronic skin or e-skin is a thin electronic material that imitates human skin in one or more forms. Specifically, human skin can detect pressure and temperature, stretch and heal itself. The electronic skin aims to apply these functions to robotic and health applications.
In July 2013, a different UC Berkeley team announced that they had created an electronic skin that lights up when played. The pressure caused a reaction in the skin that illuminates the blue, green, red and yellow LEDs; as the pressure increased, the lights became brighter. The material was composed of synthetic rubber and plastic and was thinner than a piece of paper. Interleaved between layers, the organic LEDs were illuminated with carbon nanotubes enriched in semiconductors and a conductive silver ink. The skin was made up of hundreds of circuits, each of which contained a pressure sensor, a transistor and a small LED. The pressure changed the resistance of the sensor and, therefore, modified the amount of electricity flowing to the LED.
Berkley's team suggested that the invention could be useful in artificial skin for prosthetic limbs, attached to human skin to monitor health and used in robotics. The invention was announced in Nature Materials. Previously flexible sensors and flexible screens had been demonstrated, but never at the same time.
Also in 2013, the University of Cincinnati reported the first artificial skin capable of sweating similar to natural sweat rates and with the surface texture and moisturizing properties of normal skin. Although not electronic, this microfluidic skin may allow the electronic skin to have a better grip on the skin with a slight sweat, similar to the way in which the palm and the tips of human fingers expel small amounts of eccrine sweat during the grip .
