Electronic skin refers to flexible, stretchable and self-healing electronics that are able to mimic functionalities of human or animal skin. [ 1 ] [ 2 ] The broad class of materials often contain sensing abilities that are intended to reproduce the capabilities of human skin to respond to environmental factors such as changes in heat and pressure.
The skin can be considered as a bilayer of epidermis and dermis. The epidermal layer has a modulus of about 140-600 kPa and a thickness of 0.05-1.5 mm. Dermis has a modulus of 2-80 kPa and a thickness of 0.3–3 mm. [ 5 ] This bilayer skin exhibits an elastic linear response for strains less than 15% and a non linear response at larger strains.
Sensitive skin, also known as sensate skin or electronic skin (e-skin), is an electronic sensing skin placed on the surface of a machine such as a robotic arm.The goal of the skin is to sense important environmental parameters—such as proximity to objects, heat, moisture, and direct touch sensations.
University of Texas researchers are working on 'e-skin' technology similar to human skin. The latest model has stretchy material, touch sensors. New 'e-skin' mimics human skin and could one day be ...

Wei Gao / CaltechOur future robotic overlords may be closer to acquiring a human-like sense of touch, but they’re also closer to moving beyond that—and attaining a superhuman ability to sense ...
Galvanic skin resistance (GSR) is an older term that refers to the recorded electrical resistance between two electrodes when a very weak current is steadily passed between them. The electrodes are normally placed about an inch apart, and the resistance recorded varies according to the emotional state of the subject.
The skin can be modeled as bilayer, composed of an epidermis having Young's Modulus (E) of 2-80 kPa and thickness of 0.3–3 mm and a dermis having E of 140-600 kPa and thickness of 0.05-1.5 mm. Together this bilayer responds plastically to tensile strains ≥ 30%, below which the skin's surface stretches and wrinkles without deforming. [87]
