Humans have five(5) senses. The sense of sight, smell, hearing, taste and touch. We live our lives with these senses which helps and ables us to determine everything that surrounds us.

 

Senses are very important to ourselves especially when a tragic happens and you happen to lose a particular functiom of a sense. Just for example a fire accident occured and it so happen that your skin was burn down. You might lose a sense of touch.

 

However, with this new generation and new techonology that we can use, there is an alternative solution that are developed. Read more below.

Extraordinary Artificial Skin Can Transmit Sense Of Touch To Brain Cells

Even though there have been incredible advancements in the field of prosthetics, including some more unorthodox ones, those who are unfortunate enough to lose a body part will be unable to replicate the sense of touch with their artificial limb. A remarkable new study by a team of Stanford University engineers, published today in Science, has perhaps begun to finally address this problem: they have created a plastic skin that can “feel,” transmitting sensory information as an electric signal to the brain.

 

Lead researcher Zhenan Bao had previously spent a decade attempting to develop a material that mimics the skin’s ability to flex, heal, feel pain, and detect pressure and temperature changes in the external environment. This new study has achieved one of these goals: this novel artificial skin can detect pressure changes, essentially replicating touch.

 

“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 Bao in a statement.

 

The plastic has two distinct layers, with the upper segment containing the sensing mechanism, and the lower segment acting as the electronic circuit that transports signals to the brain. In the process, these electrical signals are converted into biochemical stimuli compatible with nerve cells.

 

The upper layer contains a pressure sensor that has the same range as normal human skin, meaning that a small poke and a sharp prod can be differentiated between. It is comprised of an extremely thin, springy, waffle-shaped plastic polymer, and is very sensitive to any compression. By measuring the minute molecular compression of the plastic, a very precise pressure reading can be made.
