Design of a capsule wireless endoscopic MEMS and study on its working life

During the design of a capsule wireless endoscopic MEMS,through theoretical analysis and experimental test,it studies on the problems about all the factors that influence the working life of the endoscope system,such as image sensor selection,wireless transmission circuit configuration,control manner selection,and the design of the power system. CMOS image sensor was selected,wireless transmission power was precisely configured,flexible and power-saving magneto control manner was designed,and power system assembled of Li-Mn button batteries was selected. A wireless endoscopic MEMS with mini-size, easy-control manner,good image quality,and long working life capsule is finally manufactured. And the images that captured in laboratory and animal experiment show that the design is feasible.
