The cipher disk comprises: a base layer, a conductive fluid electrode layer, and a packaging layer; several fluid conductive electrodes are installed on the base layer, and the packaging layer The base layer and the conductive fluid electrode layer are encapsulated, and both the base layer and the encapsulation layer are made of ECOFLEX series silicone rubber; the realized device has superelasticity and flexibility, and can be completely attached to any complex curved surface, such as human skin, and has With good biocompatibility and comfort, the device realized by the present invention has self-driving characteristics, and can directly convert external mechanical input into electrical signals, thereby realizing self-generating and self-supplying characteristics.

Description

technical field [0001] The invention relates to the technical field of cipher disks, in particular to a self-driven hyperelastic cipher disk with adaptability to any curved surface and a preparation method thereof. Background technique [0002] A password disk is a human-computer interaction device widely used in the security field. In fact, cryptography was used to encode information as early as ancient Roman times. With the rapid development of modern electronic products, whether it is in the field of national defense security, or in the service industries such as communication, transportation, and industry and commerce, higher requirements have been put forward for the encryption disk technology. As an encryption tool, how to implement a low-power portable cipher disk has become a difficult point in this research field. [0003] The manufacturing process of traditional mechanical cipher disks is complicated, and each component is usually made of metal, plastic and other...
