Engineers create artificial skin that can feel what it touches

Engineers have created an artificial skin that can tell how hard it is being pressed and send that information straight into the brain.
The researchers hope that the creation of the new sensor could be another step towards creating an entire virtual skin — a flexible fabric full of sensors that could be put over a prosthetic limb, making it work something real skin.
"This is the first time a flexible, skin-like material has been able to detect pressure and also transmit a signal to a component of the nervous system," said Zhenan Bao, a professor of chemical engineering at Stanford, in a statement.

Bao has spent the last decade attempting to make a material that matches the characteristics of skin. Our bodies have the ability to flex freely, heal, and can send very fine information about what they touch to the brain — all qualities that have proved difficult to replicate in artificial ways.

The new sensing skin is made up of two layers: a sensing mechanism on top, and a bottom layer that sends the electric signals that are generated to the brain, in a way that it can understand them. It is maed up of “waffled nanotubes”, which are a series of tiny structures that get pushed together when pressure is applied, allowing more electricity to be conducted.
At the moment, pressure is all that the skin can sense — and there are six different sensing mechanisms in the hand. The engineers behind it hope that they can develop others that will allow the artificial skin to feel texture and differentiate between different materials, for instance, or detect temperature.
Because of the two-layer approach, engineers say that they will be able to add more sensing capabilities as they develop them.

Why Education is importent In india:

In India today, 4% of our children never start school. 58% don’t complete primary schools. And 90% don’t complete school. At Teach For India, the fact that only 10% of our children go on to college both saddens and angers us.

Teach For India exists because of a deep belief that every child can and must attain an excellent education. Teach For India exists to prove that no child’s demographics should determine his or her destiny. To us, the end of educational inequity is the freedom for all children to have the opportunity to reach their potential. And the day that all children reach their potential is the day that India reaches her potential.

Teach For India believes that that day will come in our lifetime.

Teach For India believes that it will take a movement of leaders with the idealism, belief, skills and commitment to actualize this vision. We are committed to finding, developing and supporting India’s brightest, most promising leaders for this to happen
