A memristor based ultrasonic transducer: The memosducer

We suggest an experimental realization for a new concept of chaotic transducer based on memristors and specifically devoted to the optimization of ultrasonic excitation involved in nonlinear time reversal based ultrasonic imaging. The design utilizes hysteretic properties of a Knowm Inc memristor, considered as the new key electronic component used in mimicking elementary cells plasticity and biological neuronal systems as humain brain. Due to the memristor ability to include nonlinear and memory based properties in the time domain, complex time delays activated by a suitable distribution of array of memristors is equivalent to the acoustic response of multiple scattering and multiple reflections in waves guides as inside chaotic cavities. Instead being an hindrance, it actually improves the focusing properties of the Time Reversal (TR) based Nonlinear Elastic Wave Spectroscopy (NEWS) methods aim at measuring local nonlinear signature of complex damaged systems. Consequently, the memristor based TR-NEWS device induces a new focusing family of ultrasonic transducers modified by the presence of memory properties. Like the memcapacitor and the meminductor, the memosducer constitutes the memory based improved new generation of ultrasonic transducing devices devoted to nonlinear acoustic imaging.
