| Summary: | 碩士 === 南開科技大學 === 車輛與機電產業研究所 === 104 === This research applies electromyography (EMG) collection circuit to daily exercising equipment and physiotherapy equipment. People use muscles during activities in daily life, especially engaging in physical movements. Some physical movements require the engagement of large group of muscles. Overusing them for a long period may lead to sore and injury. We can observe the fatigue extent of muscles with the help of EMG. Signals will be generated once certain voltage is approached. We thereby use the signals to control the slope of the stretch board. This project is applied to stretch boards, and with some improvements for the stretch boards sold in the market, some unnecessary injuries can be prevented while stretching one's muscles. Our purpose is to prevent muscles from harmful pulls, and besides monitoring muscles, it also has the function of stretching gradually. It halts at multiple angles and won't be troublesome adjusting manually for each angle. Automatically and slowly increasing angles or reducing angles produces the effect of helping people avoid abrupt harmful pulls while stretching muscles. This project also uses single chip control which we further use to design the smart treadmill. When trampling the pedals, we can control the degree of muscles stretching from loose to tight as well as simulating climbing steep mountains. In addition, the use of the load can applied to measuring user's weight and then customize the extent of tightness according to the weight.
