Abstract:
Objective To discuss the application of image sensor in wireless endoscopic micro-electro-mechanical-system (MEMS). Methods Through the comparison of various types of image sensors, and in the consideration of the environment and requirement inside the body, CMOS image sensor which can output analog image signal with high density of integration, low power consumption, small profile was chosen as the sensor component of a wireless endoscope. The profile and power consumption of some specific models of this type of image sensor were compared and analyzed.Results The problems, such as ground connection, crystal configuration and the layout of circuit board, were reasonably solved during the design of image sensor's schematic circuit diagram. The image capture module based on OV7930 sensor was designed and manufactured. Images were successfully captured during the animal experiments.Conclusion The application and design of image sensor in a wireless endoscopic MEMS are feasible.
