When some stimulus exist, nerve of living things catches them as information and muscle responds immediately to lead living things in security. Our research has an object to make structure as simulated living things; in other terms, make a smart structure which includes sensor and actuator corresponding to nerve and muscle, respectively.
Until today, vibration information had been taken by a sensor which can collect only from specific point. Control by using point information sensor has problems, such as problem on distinguish vibration modes or problem on amount of information, so that there remind some difficulties on construction of control system.
The subject here is to realize a stable control system by using smart sensor and actuator (actuation system). First, let a sensor itself sort out factors which harm structures, using 2D sensor made of PVDF film. Second, at the same time, generate distributed actuation system without causing instable phenomenon of structure. Smart structure with higher safeness for structure is on development by realizing the series of movements above-mentioned.
