SAW Devices for Reservoir Computing

 We are developing SAW (Surface acoustic wave) devices which are one of MEMS, for integration of two concepts, physical reservoir computing, which makes use of physical dynamics as a computational resource, and edge computing, which gives a role as an information processor to edge devices. In this research, we define a state of SAW in a waveguide as a reservoir state, then fabricate and design devices that can change the state by applying a voltage between the waveguide, and measure its frequency responses.
