LIME: LIquid MEtal Interfaces for Non-Rigid Interaction
summary
Room-temperature liquid metal GaIn25 (75% gallium, 25% indium) moves and deforms under an external electrical field in alkaline solution by changing surface tension. LIME builds reusable LIME cells (open, sealed, tunnel) with embedded electrodes and demonstrates widgets: a 3x3 pixel 3x3 matrix that changes surface tension for deforming keys, a transparent/opaque matrix, a physical slider, checkbox and radio-button behaviors, and dynamic haptic pulses. Prototypes work electrically; tunnel cells enable controlled droplet transfer.
