| Research Abstract |
We have proposed to create new-type electronics (Biotronics) which is learned from bio fluctuation. As one of examples of controllable physical fluctuation system, we will fabricate spin and/or dipole frustrated materials. Based on new physical properties coming form co-existence of competed phases and "Yuragi" (frustration system), it will be developed that flexible and adaptable information system and devices originated from bio-inspired system. Regarding present electronic devices represented by C-MOS type FET, effort has been aimed at the reduction of size according to the Scaling Rule, high integration, and the realization of high speed information processing. Therefore until now, "strict and precise control" and "structural order control" have been realized with an enormous amount of effort. By referring to biological systems, this research will aim to realize novel devices (information processing devices, memory devices) that actively utilize "Yuragi" and "randomness", which were previously thought of as impediments. We have demonstrated that preliminary works on "Biological Function Imitating Devices : Stochastic Resonant Devices" by using organism innate "Information Yuragi : information processing principles based on stochastic resonance phenomena" ; all of which are based upon ideas completely opposite of traditional conceptions.
