A research team at Japan's Keio University has successfully engineered a flexible optical tactile sensor. This innovative sensor is adept at simultaneously detecting both the position and intensity of applied pressure. Boasting exceptional sensitivity and stability, its response time peaks at an impressive 33 milliseconds. The sensor's dimensions are 5 cm in length, 1.5 cm in width, and 500 micrometers in thickness. It incorporates a four-channel design, facilitating precise localization of pressure points and offering scalability. The team utilized the "mosquito needle method" to craft polymer optical waveguides, which not only enhances the flexibility in waveguide structure design but also allows for precise control over sensor sensitivity. Experimental results reveal that the sensor achieves a sensitivity range of 8.7 to 10.9 dB/MPa, underscoring its outstanding performance. This cutting-edge technology shows great potential for use in next-generation robotic tactile interfaces, advanced medical diagnostics, and wearable electronic devices. It provides robotic systems with high-precision tactile feedback and can be seamlessly integrated into bionic prostheses, enabling a sense of touch.
