The market size of six-dimensional torque sensors is growing rapidly, and domestic manufacturers continue to make efforts

KJ3242X1-BA1 The force sensor market space is large, and the size of the six-dimensional force sensor market is expected to grow rapidly. According to Beziers Consulting data, the global force and torque sensor market size in 2022 is 57.24 billion yuan, and it is expected to reach 80.483 billion yuan in 2028, and the CAGR from 2022 to 2028 is expected to be 5.84%. In 2022, the demand for six-dimensional torque sensors in China’s humanoid robot market is 8360 sets, and the market size is about 156 million yuan. With the accelerated development of humanoid robots, the market size of six-dimensional torque sensors is expected to grow rapidly.

The gap between domestic and foreign leaders in the field of force control sensors is large, and domestic Yuli and Kunwei are relatively leading. According to the data of Gaogong robot, in 2022, China’s force sensor market is still dominated by foreign brands, and the domestic share is less than 30%. Domestic manufacturers mainly include Yuli Instrument (not listed), Kunwei Technology (not listed, aerospace grade technology), Keli Sensing (layout of high-end torque sensing), KJ3242X1-BA1 Donghua Testing (leading force sensor technology), etc. There are mainly ADI, ST and TDK in foreign countries.

3. Flexible sensor: Electronic skin or the ultimate solution for tactile sensing

3.1. The flexible sensor is composed of a flexible substrate, a thin film material, etc

Flexible sensors are sensors made of flexible materials that can be used in a variety of specific scenarios. The flexible material corresponds to the rigid material, with soft, low modulus, easy deformation and other properties, the corresponding flexible sensor has good flexibility, ductility, can be freely bent or folded, the structure is flexible and diverse, and can still show good electrical conductivity and responsiveness in the bending and stretching form. Thanks to its excellent performance, flexible sensors have become an important part of modern flexible electronic products, and are widely used in electronic skin, healthcare, electronic and electrical, sports equipment, textiles, aerospace, environmental monitoring and other downstream fields.

The flexible sensor is mainly composed of a flexible KJ3242X1-BA1 substrate, a thin film material and an electrode. 1) Flexible substrate: Commonly used flexible sensors mostly use PI (polyimide), PET (polyester) or PEN (polynaphthalene dimethyl glycol ester) as the flexible substrate of the device. PI is one of the organic polymer materials with the best comprehensive performance, with good mechanical properties, tensile strength above 100MPa, dielectric constant no higher than 3.5 (after special treatment can resist 2.5), temperature point up to 250℃ and can be used for a long time, and has excellent radiation resistance and chemical resistance. PET is a kind of saturated thermoplastic polymer, long-term use temperature up to 120℃, has good optical properties, excellent wear friction, dimensional stability and electrical insulation, and oil, fat, acid/alkali resistance, low price, large yield, good mechanical properties; PEN is a new and excellent polymer, which has higher physical mechanical, gas barrier and heat resistance than PET, long-term use temperature up to 160℃, and has ultraviolet and radiation resistance.
