| Summary: | 碩士 === 逢甲大學 === 電機工程所 === 97 === How does the rehabilitation for injured hand or fingers recover to the normal function, is great challenge for the physician and physiatrist to evaluate. In order to access the hand motion and manipulating function, an interactive and friendly computer interface measurement device that is capable of measuring the force of finger adduction and abduction or opposition of between thumb and fingers will be helpful for physician to diagnose and treat a patient. The motive of this thesis is then to design a hand function force measurement device with computer interface for the metacarpal force measurement.
The hand function force measurement system with computer interface designed in this thesis is basically an USB microcontroller-based system, it consists of a pinch force measurement device and a revolving force measurement device. The pinch force measurement device consists of a force sensing resistor, an instrumentation amplifier, voltage regulator, analog to digital converter, monitoring device, and a microcontroller. The revolving force measurement device is designed and implemented by a DSP-based motor control device. Each unit of the force measurement sensor circuit is designed well and simulated by circuit simulation software. Furthermore, the hardware circuits of each unit are integrated and also the software programmed are edited and complied to execute. Finally, a prototype of hand force measurement system based on microcontroller is implemented and demonstrated.
