This invention provides a wireless, passive force-position implantable growth monitoring system and its fabrication method for early-onset scoliosis correction. The system includes: a connected compressible capacitive sensor and a flexible wireless antenna coil; the compressible capacitive sensor is connected to a self-growing early-onset scoliosis correction implant growth rod, and the flexible wireless antenna coil is disposed within the body. The compressible capacitive sensor and the flexible wireless antenna coil together constitute an LCR resonant circuit; the compressible capacitive sensor monitors the pressure changes caused by the elongation of the self-growing early-onset scoliosis correction implant growth rod during tissue or bone growth, thereby causing changes in capacitance and resulting in changes in the resonant frequency of the LCR resonant circuit; the resonant frequency change is detected and read out wirelessly via an external readout device. This system is designed to meet the needs of digital rehabilitation, requires no internal power supply, and has a stable structure, making it suitable for growth monitoring after early-onset scoliosis correction surgery.

A double-flying linkage up and down riding lever-type driving device for bicycles belongs to the field of bicycle manufacturing technology. The structure is composed of a device housing, a bearing seat, a central axis, a driving rod, a belt, a spring, a rotating wheel, a crank, etc. The invention has a novel structure and a clear working principle. The central axis is driven to rotate by the up and down swinging of the left and right cranks, the driving rod is driven to swing up and down by the central axis, the belt is driven to extend and retract by the driving rod, and the rotating wheel is driven to reset by the spring. Compared with the traditional bicycle driving structure, the present invention can realize single-side independent driving and double-side alternating driving. When driving, the previous pedaling circle action mode is changed to an up and down action mode. After the pedal is stepped on, it is automatically reset by the spring, which solves the problem of dead point position effort during traditional bicycle driving, saves the physical strength of the rider, and further improves the riding efficiency. The key is that it is easy to operate and further meets the riding needs of different groups of people, especially those with leg disabilities.

This invention discloses a cable tensioning device, method, and application for large-angle vertical rotation of long linear structures, belonging to the technical field of installation devices for large-angle vertical rotation of long linear structures. Located at the cable anchorage end of the higher part of the vertical rotation component, it includes a cable force identification module, a mechanical transmission module, and a tensioning module. The cable force identification module includes several force measuring elements, each disposed on each strand of the cable.
