Korean researchers have developed a soft, stretchy skin-like electronic material that can be used to wirelessly send signals to soft robots.<br />Park Se-young has more. <br /> Fingers connected to this electronic skin bend and straighten just like real fingers.<br />The e-skin, less than a millimeter thick, receives command signals through its wireless communication chips.<br />The system is based on fully printable, stretchable hybrid electronics that can operate even when the skin is pressed and folded.<br /><br /> "We implemented the system using the smallest communication chips and antennae. Since each chip is connected with elastic electrodes, the system operates properly even when its shape is altered."<br /><br /> The light bulb stays on even when the wire is stretched out.<br />After hardening a water-like hydrogel, a layer of rubber was spread thinly to maximize the material's elasticity.<br />Then, silver ink was used to electrify the material for use as a wire.<br /><br /> "Currently, it can stretch to 18-point-eight times its original length. The previous technology could only be stretched five or six times its length, so it's a huge improvement."<br /><br />These stretchy materials can be used for both wearable devices and soft robots.<br /> Those soft robots, which can be used for exploration and rescue in hard-to-reach areas, are expected to evolve along with the development of this new material.<br />Park Se-young, Arirang News. <br />
