A Korean research team has developed a high-performance tactile sensor that can feel delicate touch like a human. Because it can distinguish fabric from feel, it will greatly contribute to the development of medical devices such as prosthetics and robots for next-generation services.
A team of researchers from Pohang University of Science and Technology Professor Kim Jong-kyu and Professor Park Wan-joon of Electronic Computer Communication Engineering at Hanyang University have developed a "artificial fingerprint sensor" that responds sensitively to pressure and vibration.
The reason why robots cannot follow hands is because they have no sense. Although efforts have been made 토토사이트 to develop high-performance tactile sensors, they have not developed sensors that distinguish material's texture. Although many polymers are used to detect pressure, it has been confirmed that research does not detect vibration sensitive.
The researchers created a pressure device that can simultaneously detect subtle pressure and vibration in the way humans feel touch. First of all, it produced ultra-small springs that are nm (nanometer) and 1nm (1 billionth of a meter) using special metals called indium tin oxide. It also created a ultra-small pressure sensor that changes the elasticity of a spring into an electric signal. The sensor is placed in the form of a finger fingerprint. This is to effectively detect the texture of an object.
