Abstract
This application provides a flexible tactile sensor, its fabrication method, a tactile sensing system, and its applications. The flexible tactile sensor includes a contact layer and a pressure sensing component. One side of the contact layer has a fingerprint structure. The pressure sensing component includes a first electrode, an ion membrane, and a second electrode. The ion membrane is sandwiched between the first and second electrodes and forms an ion-electron interface double-layer capacitor with both the first and second electrodes. The contact layer is attached to the side of the first electrode away from the ion membrane, and the fingerprint structure is located on the side of the contact layer away from the first electrode. The fingerprint structure mimics human fingerprints to effectively capture vibrational stimuli during interaction, enabling the device to recognize or detect external objects. The combination of the fingerprint structure and the pressure sensor component gives the tactile sensor a sensitive ability to recognize external objects (or textures).
