Chinese Scientists Create Flexible Sensor Sticker for Gesture-Based Communication and Assistive Technology

Scientists in China have developed a thin, flexible adhesive sensor that can detect subtle movements of hands, fingers and mouth and translate them into words or commands. The wearable sensor, made of soft silicone rubber with integrated fiber optic cables, is designed to be comfortable for everyday use and support assistive technologies for people with disabilities or limited mobility.

The sensor works by detecting changes in the wavelengths of light that travel through fiber optic cables when they are bent or stretched by movement. Even the slightest gestures, such as bending a finger or twisting a wrist, can be recognized accurately. In the experiments, volunteers could send messages in Morse code by bending their fingers and silently articulate vowel sounds by moving their cheeks.

Researchers imagine that sensors will be integrated into clothing, accessories, or even directly into the skin to allow for more natural interaction with digital devices. Potential applications include communication aids for the disabled, vital signs monitoring, enhancing athletic training, and enabling immersive, gesture-controlled gaming experiences. Future work aims to make sensors smaller, more durable, wireless and tailored to individual needs.
