We have been trying to realize bioinspired stochastic signal/information processing devices. With an analog electronic circuit, a network device with hierarchical instability is implemented using threshold units with hysteresis. In order to drive the device using molecular noise generator, we fabricated stochastic capacitors, which are composed of binary mixture of semicrystalline polymer with liquid crystalline molecules. We succeeded in emergence of molecular-noise-driven coherent resonance phenomenon in the circuit.
