Surface acoustic waves device
Webwork, we propose controlling magnetic skyrmions by electric-field-excited surface acoustic waves in neuromorphic computing device structures. Our micromagnetic simulations show that the number of created skyrmions, which emulates the synaptic weight parameter, increases monotonically with increases in the amplitude of the surface acoustic waves. WebPROBLEM TO BE SOLVED: To provide a surface acoustic wave device biosensor capable of detecting a process of propagation-growth-injury repairing of a cell, which is observed conventionally only by an optical microscope, by measuring it as a surface acoustic wave (SAW) propagation characteristic due to physical and chemical changes of the cell …
