Abstract

In this paper, the integration of interdigital transducers, MEMS and smart electronics is presented with examples including systems for (1) noise suppression in buildings, aircraft cabin, etc. using `smart wall paper', (2) drag sensing and reduction in aircraft, (3) early warning from collapsing bridges, overhead highways, etc., due to earthquakes, flooding, etc., to the approaching vehicles and automatically stopping the vehicles before the damage location, (4) automatic impedance matching for cellular phone communication thus avoiding any interference from other unwanted signals, magnetic fields from the power lines, etc., (5) diesel fuel pollution sensing and control, (6) drip irrigation and (7) deflection and strain measurement of flex beam structure in helicopters. A theoretical analysis and an experiment relating to the later is presented in detail.
