Flexible tactile sensor lets robots feel

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed a tactile sensor composed of silicon and carbon materials that can serve as a skin for robots, absorb shocks, and differentiate between various forms of touch. The researchers combined silicon and carbon nanotubes to produce a composite, which was paired with a medical-imaging technique called electrical impedance tomography. The team says the new material can distinguish between the location and the size of various forms by touch. In addition, it can withstand strong force, as well as function as a three-dimensional computer interface and tactile sensor. The researchers also note it can be reused even after partial damage to the sensor by filling and hardening the damaged region with composite. “This technology will contribute to the soft robot industry in the areas of robot skin and the field of wearable medical appliances,” says KAIST professor Jung Kim.
