A micro-camera which is the size of a large grain of salt has been developed by The Fraunhofer Institute for Reliability and Micro integration (IZM) in Berlin, Germany for use in disposable endoscopes.
By reworking the electrical wiring to the individual parts of the sensor to go through the back of the wafer rather than the side researchers minimized the image sensor's size. Usually the location of the sensor is at the base of the endoscope. The sensor's size has been reduced to such an amount that it can be mounted on the endoscope's tip.
