Drastic improvement of performances of today’s aircraft and automotive require a multi-functional design including functions of mainframes, sensors, actuators and power sources like biological structures. We have studied on the basic mechanism of functional materials such as optical fibers and piezoelectric materials and the applications to future structures. Our research results contribute reduction of energy consumption and safety improvement of various machines.
