Japanese scientists have demonstrated a super flexible electronic skin (e-skin) display that is made from organic electronics and doesn’t degrade when exposed to air.
Takao Someya said that this e-skin can be directly laminated on the surface of the skin, allowing it to electronically functionalize the human skin.
He even elaborated that this e-skin can replace the smartphone in the future, and smartphone are bulky device but if the e-skin functionalize our own skin, we don’t need to carry anything and it will be easy to receive information anywhere, anytime.
Someya’s group extended the device’s lifetime to several days by creating a protective film, called a passivation layer that consists of alternating layers of inorganic silicon oxynitride and organic parylene.
This film protects the device from damaging oxygen and water vapor. Researchers said that it is so thin that the device is just 3 micrometers (millionth of a meter) thick and highly flexible compared to a strand of hair which is 40 micrometers thick.
It is believed that the goal of the researchers with this electronic wearable may integrate with the human body to enhance or restore body function for biomedical applications.
