ã€Chinese instrument network instrument research and development】 Recently, Professor He Xiaodong and Professor Wang Rongguo of the Institute of Composite Materials and Structures, Harbin Institute of Technology Harbin Institute of Technology, published a research report on “hair-skin†sensors based on human real skin structure. Association of Applied Materials and Interface Journal (Impulsion Factor 7.145). The project was funded by the National Natural Science Foundation and other projects.
The skin is one of the most important human sensory organs. Scientists have been working on developing sensors that are close to human skin so that robots can perceive the world as humans do, for example, grasping objects and sensing slipping, sensing gas flow velocity, and distinguishing between soft and hard objects. Wait. The existing design models for artificial skin sensors are all based on smooth skin, using a variety of nano-cells or structures to achieve high-sensitivity sensing, but there are deficiencies in range or structural durability.
Harbin Institute of Technology smart artificial skin sensor's hair part uses cobalt-based glass to cover the magnetic fiber, and the skin layer uses artificial silica gel; the magnetic field induced by the alternating magnetic field excites the coupling magnetic field to induce the change under the external stress to induce, the sensor has high Sensitivity (feature of 0.15 millinewtons can be sensed), ultra-large range (0.15 millinewtons to 25 nanonewtons), perceivable gas flow rate, repairability, ability to perceive and evaluate properties such as hardness of materials by pressing; The simultaneous excitation of the variable magnetic field can be used to evaluate the electromagnetic properties of the material and to distinguish the material properties (distinguish the magnetic body, non-magnetic conductor, and insulator) while sensing the pressure.
At present, most of the artificial skin sensors do not have an assessment of material properties. Harbin Institute of Technology's “skin-skin†sensor has been initially applied to determine the size of friction during robot gripping, and it has potential application prospects in the robotics field in the future. Professor Tsuyoshi Takebetsu, a renowned scholar in the field of flexible devices and professor at Osaka Prefectural University, commented: “The detection range of the 'sweep-skin' sensor is impressive, and its design philosophy is unique.â€
