Researchers at Northwestern University have devised a way to mimic the sensation of human touch with an epidermal VR device. Featuring an array of tiny, vibrating, programmable components called actuators, the device adheres to a user’s skin like a bandage, using a silicone polymer material. The device can be placed anywhere on the body. The number and placement of devices depends on how the technology is used and for what purpose.
Although the battery-free device currently weighs just a few grams per every 10 square centimeters, Rogers says the platform will get thinner and lighter. Ultimately, users can wear the device like a fully programmable second skin. Once it’s ready for mass manufacturing in a couple of years, the device could be tailored to any size and shape and could also even heat and cool the skin to more closely mimic the sensation of warmth from another person’s fingers.
