Those “Tickle Me Elmo” dolls might just get a whole lot creepier now that scientists have developed an electronic skin that can feel different sensations like tickling.
An international team of researchers have published a paper in the journal Science Robotics on Wednesday detailing their study into the creation of a bioinspired robotic skin. The material uses different sensors coupled with a machine-learning neural network in order to detect pressure and vibrations. The team believes that it can be utilized on robots to help them get better sensory feedback about their surroundings, as well as on future prosthetic devices for humans.
The skin itself is made of two layers: a top layer made of a rubber-like polymer that imitates the outermost layer of human skin (called the epidermis), and a bottom layer made of a hydrogel that imitates the layer of the human skin below the epidermis (called the dermis). The dermis-imitating layer contains a number of tiny electrodes that can detect pressure on the robo-skin.
It also houses small microphones that “are used to sense vibration due to touch,” Kyungseo Park, a robotics researcher at the Korea Advanced Institute of Science and Technology and the lead author of the paper, told The Daily Beast. “It allows the robotic skin to feel light touches, such as pat, tickle, stroke, and so on.”
