On-off sensors based on strange attractors

In this work the possibility of coupling a new class of materials with nonlinear dynamic circuits to design a new class of on-off sensors is discussed. The results that are included are preliminary and cover several applications. We consider post-silicon materials like polymers and solution-based devices to design new types of on-off sensors. The key idea is to link the variation of a quantity detected by the material to the change of a parameter of a chaotic circuit, so that to exploit the parameter sensitivity of chaotic circuits. A proof of concept is given in this work, by showing several experiments based on different types of innovative materials/devices, such as clevios, IPMC and water solution cells.
