Zusammenfassung: | Coupling integration devices have been widely investigated in order to realize advanced artificial intelligence. In particular, by varying the mechanical energy of the sensory memory, the external force causes the alteration of internal energy and exerts an effect on its electrical properties. The goal of converting artificial touch into electronic implementation is to achieve perceptual intelligence, and it would profoundly advance a wide range of applications, such as robotic grasping tools, prosthetics, and human-computer interaction. Here, we focus on the recent progresses in electromechanical coupling memory and their applications in tactile sensory memory and artificial synapses. Also, electromechanical sensory memories are analyzed in terms of deformation-involved physical mechanisms, including the piezoelectric effect, piezoresistive effect, and triboelectric effect. Deformation-involved functional sensors integrated with memristors are also discussed for the artificial tactile memory applications. In addition, pressure-tunable synaptic functions and artificial memory skin emulated by electromechanical memories are discussed in details. At last, the application prospect is shown and challenges are also exist in aspects such as multilevel storage, energy consumption, and sensitive degree, which would further disclosure the merit and demerit of electromechanical integrated devices.
