Gloves with electronic sensors that convert hand movements into information are currently under development. However, making sensors waterproof for use in the pool or ocean while maintaining flexibility and wearability is challenging. Inspired by the starfish’s tube feet, the researchers created waterproof sensors by placing them on a thin film of polydimethylsiloxane (PDMS), a waterproof plastic commonly used in contact lenses. They developed a prototype by collecting 10 of these sensors in self-adhesive bandages and attaching them to the joints.

For the demonstration, researchers recorded 16 gestures, including “OK” and “Exit.” The machine learning program converted these movements into messages with 99.8% accuracy. In the future, such gloves could help divers communicate with each other using visual hand gestures, even when they cannot see their partners underwater.
