A truly high-tech solution for cleaning chip surfaces of digital SLR cameras: statically charged brushes. One brush stroke, then recharge the brush with compressed air to build up static electricity for 5-10 seconds. That sounds like very time-consuming work for cleaning the chip. Somehow I would find it better if manufacturers finally tackled the problem directly in the camera, the way Canon does with apparently less electrostatically charged CMOS sensors or Olympus with their ultrasonic cleaning system.
