Nano-synchronized sensors have been around for many years, but they have been large and relatively expensive. A multi-channel system developed by DELTA in Denmark in 2007, required a quarter 19-inch rack.
The latest Aerial Sensor fills a single circuit board the size of an A4 sheet of paper, and we expect the next generation will be smaller than a mobile phone. This high performance sensor will be flown behind wind turbines as described here. Based on future technology roadmaps, we expect miniaturized nano-synched sensors will available in the 2015- time frame, transducers the size of a golf ball.
