Artificial throat could someday help mute people 'speak'

Most people take speech for granted, but it's actually a complex process that involves both motions of the mouth and vibrations of folded tissues, called vocal cords, within the throat. If the vocal cords sustain injuries ...

Boosting the 'brains' of computers with less wasted energy

Many internal components used in today's computers reach temperatures that are hot enough to cook a Thanksgiving meal. The heat produced by the computations can easily burn human skin and tissue – and much of the heat is ...

Electronic glove gives robots a sense of touch

Stanford engineers have developed an electronic glove containing sensors that could one day give robotic hands the sort of dexterity that humans take for granted.

Skin hardness to estimate better human thermal status

Under the same temperature and humidity, human thermal status may vary due to individual body constitution and climatic environment. A KAIST research team previously developed a wearable sweat rate sensor for human thermal ...

E-skin able to detect changes in wind, water drops and moving ants

A team of researchers working at the Chinese Academy of Sciences has developed an electronic skin that is sensitive enough to detect changes in air moving, falling drops and moving ants. In their paper published in the journal ...

Ultrathin electronic tattoos for wearable computing

Researchers at Carnegie Mellon University's College of Engineering are using an off-the-shelf printer to develop robust, highly flexible, tattoo-like circuits for use in wearable computing.

E-whiskers may be touchstone for future of e-skin

Those cute little whiskers you see on your pet do more than just twitch adorably. The long, protruding hairs are actually touch receptors, sending vital information about the surroundings to the brain and helping the animals ...

Skin

The skin is the outer covering of the body. In humans, it is the largest organ of the integumentary system made up of multiple layers of mesodermal tissues, and guards the underlying muscles, bones, ligaments and internal organs. Skin of a different nature exists in amphibians, reptiles, birds. Human skin is not unlike that of most other mammals except that it is not protected by a pelt and appears hairless though in fact nearly all human skin is covered with hair follicles. The adjective cutaneous literally means "of the skin" (from Latin cutis, skin).

Because it interfaces with the environment, skin plays a key role in protecting (the body) against pathogens and excessive water loss. Its other functions are insulation, temperature regulation, sensation, synthesis of vitamin D, and the protection of vitamin B folates. Severely damaged skin will try to heal by forming scar tissue. This is often discolored and depigmented.

In humans, skin pigmentation varies among populations, and skin type can range from dry to oily. Such skin variety provides a rich and diverse habit for bacteria which number roughly a 1000 species from 19 phyla.
