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.
Â The resolution of the
camera is 25,000 pixels and measures 0.7x0.7x1.0 mm. The micro-camera is
expected to be manufactured by 2012 only for few euros.
