摘　　要：Mimicking tactile perception is critical to the development of advanced interactive neuromorphic platforms.Inspired by cutaneous perceptual functions,a bionic tactile perceptual platform is proposed.PDMS-based tactile sensors act as bionic skin touch receptors.Flexible indium tin oxide neuromorphic transistors fabricated with a single-step mask pro-cessing act as artificial synapses.Thus,the tactile perceptual platform possesses the ability of information processing.Interestingly,the flexible tactile perception platform can find applications in information encryption and decryption.With adoption of cipher,signal transmitted by the perception platform is encrypted.Thus,the security of information transmis-sion is effectively improved.The flexible tactile perceptual platform would have potentials in cognitive wearable devices,advanced human-machine interaction system,and intelligent bionic robots.
