A micro-force measurement system based on high-temperature superconducting magnetic levitation

A cryogen-free portable 3 T high-temperature superconducting magnet for an electromagnetic property measurement system has been developed to serve as a user facility at the Korea Basic Science Institute. The metallic insulation method was adopted to reduce the charging delay without sacrificing the self-protecting feature. A genetic-algorithm-aided optimized design was carried out to minimize the superconducting tape consumption while satisfying several design constraints. After the design, the compact high-temperature superconducting magnet composed of eight double-pancake coil modules was wound with high-temperature superconducting tape and stainless steel tape, and integrated with a two-stage cryo-cooler. The 3 T magnet was successfully cooled to approximately 20 K with a cryo-cooler and reached the target field of 3 T without any problems. Long-term measurements and a range of other tests were also implemented to verity the performance of the magnet. Test results demonstrated the feasibility of a cryogen-free portable high-temperature superconducting magnet system for electromagnetic property measurement experiments.

Force Measurement System

According to the requirements of measurement of plantar pressure and shear stress in the meantime, this thesis puts forward a plan to construct a new insole plantar pressure and shear stress system based on multifunction data acquisition modular and Lab VIEW. Then the hardware part and software part are designed and developed respectively. There are 3 sensors are arrayed at each measurement point, that means 3 sensors are assembled in 3 different directions of X,Y and Z . The piezoelectric ceramic type sensors are designed, manufactured and calibrated according to scientific methods. Meanwhile, the DAQ card is selected carefully. Of course, the software part is developed based on Lab VIEW. A series of tests are performed in order to validate the function of the measurement system. The results satisfy the anticipated design requirements. At last, the problems and application trend of the measurement system are predicted.
