Self-powered droplet manipulation for full human-droplet interaction in multiple mediums

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Published: March 8, 2025

Droplet manipulation holds significant promise across the energy, environmental, and medical fields. However, current methods still lack a solution that simultaneously satisfies requirements for self-powered energy supply, high efficiency, human-droplet interaction, flexibility, universality. Herein, we develop interaction platform based on an omni-directional triboelectric tweezer, which directly utilizes charges induced by human motion to manipulate droplets. The tweezer produces electric field necessary droplet control through simple sliding motions, thereby eliminating conventional dependencies power source complex electrode arrays. Moreover, its operation capability further enhances flexibility precision of manipulation. Our approach demonstrates effective in both gas liquid phases hand movements, enabling range operations such as efficient transportation, precise anchoring, flexible steering, merging chemical reactions, drug extraction, showcasing comprehensive application capabilities. Here, authors It generates voltage air oil. Applications may include high-speed transport, positioning, non-invasive sample extraction.
