We developed a finger motion detection sensor based on liquid metal. The sensor was fabricated by sequentially preparing an AB glue mold (embedding bamboo sticks and acupuncture needles as internal structures), injecting liquid metal into a silicone tube, followed by functional testing. Performance characterization involved measuring resistance changes under different stretching positions and forces, with relatively stable data obtained through strictly repeated operations and video recording. This sensor holds potential application value in fields such as motion monitoring, human-computer interaction, and rehabilitation assessment.
