Recently, China's leading tactile sensor technology company: SZPX Technology released a new product: multi-array three-axis tactile sensor.
SZPX is committed to the development and production of advanced three-dimensional smart tactile sensors, and is the only multi-dimensional tactile sensor company in China.
At present, China's tactile sensor products are mainly single-dimensional resistance-capacitance film types. For example, multi-array and multi-dimensional sensors rely on foreign imports for 95%, and are expensive, bulky, and difficult to integrate and apply.
The founder of SZPX, Dr. Xu, graduated from Waseda University in Japan, under the supervision of Professor Shigeki Sugano, an authority in the field of robotics in Japan, Sugano Lab. In Sugano Lab, the world's first humanoid robot was born.
The Dr.Xu team has more than 7 years of accumulation of high-precision tactile sensors and robotic arm dexterous hand orientation technology. At the same time, it has implemented many projects with Japanese FANUC, EPSON and other leading companies. The core team members all come from leading companies in the advanced manufacturing field, with entrepreneurial and merger experience.
Because Chinese products are restricted by materials and processes, tactile sensors have been difficult to commercialize, and due to their short life and poor accuracy, tactile information and feedback are not rich enough in precision machinery manufacturing, resulting in a lack of automation.
Automated production and robotics industries have great demands for high-endurance and high-precision sensors. Dr. Xu introduced that the service life of the tactile sensor developed by SZPX can reach 200 times that of the current products on the market, and the durability can reach more than 200,000 times.
Multi-array three-axis tactile sensor, the core technology includes high-precision, low-noise tactile signal analysis system, bionic skin structure design, three-dimensional three-dimensional sensing technology and tactile database, etc.
The multi-array three-axis tactile sensor contains three key modules, namely the independently developed magnetic field sensing circuit soft board and elastic composite material, and the first tactile database.
By feeling the physical surface characteristics, the multi-array three-axis tactile sensor has five sensing dimensions of softness, friction, texture, thermal conductivity, and surface viscosity. The accuracy can reach 0.01N~19N, and the response speed is 0.1ms. The tactile resolution is approaching the limit of human skin perception of 1.2mm (human skin can distinguish between objects up to 1mm).
In 2004, the Department of Science and Technology of Keio University in Japan has begun to use soft silicone to make a hemispherical sensor that can analyze the roughness and shape of the surface of the contacted object, which is mainly used for robot fingers.
In the past two years, the scope of application of tactile sensors has expanded to the field of VR in addition to robots. After Facebook changed its name to Meta, it also recently announced a new tactile perception ecosystem. They developed a low-cost tactile sensor DIGIT, and cooperated with the touch-sensing "skin" ReSkin developed in cooperation with Carnegie Mellon University, which can allow robots to perceive the outside world more accurately, provide AI with learning data in the real environment, and understand reality. Better interaction.
At present, the application scenarios of tactile sensors are very wide, no matter in the sensing of robot manipulators, there are also extensive market demands in the fields of automation, medical treatment, wearable devices, aerospace and so on.
SZPX has obtained cooperation from several leading customers in the advanced manufacturing and textile industries, focusing on providing the only customized product of three-dimensional tactile sensors with an accuracy of 0.01N to 50N in China, analyzing tactile sensations and providing tactile digital services.
In addition to the bionic skin, Meta also released VR gloves, which can give users an interactive experience, which is also one of the directions that SZPX is developing. "It is difficult for a tactile sensor to form a closed loop, but through a tactile feedback device, it actually forms a closed loop for interaction with the user." Dr. Xu said.
Tactile perception may be one of the most important ways for humans to interact with the physical world. Without tactility, human perception will be very limited and even doubt the existence of the body. At present, the field of tactile research is still in its infancy, and SZPX's top-level tactile sensor research and development and commercial landing capabilities. The team independently developed China's only thin and light multi-array 3D tactile sensor, which has been the first to land and realize deployment. The application scenarios related to tactile sensors are extremely wide. From industrial flexible logistics production to tactile feedback in a true virtual environment, tactile analysis and tactile digitization will be a vital part of the world's development.
