Description

EGaIn (Eutectic Gallium-Indium) is a liquid metal alloy composed of gallium and indium, which remains in its liquid state at room temperature. This unique property allows EGaIn to maintain its fluidity and adapt to different shapes, making it highly versatile for various applications. When subjected to strain, EGaIn experiences a change in resistance, with the direction and magnitude of the strain determining the extent of this resistance change. Although the resistance change is relatively small, it can be precisely measured with specialized electronics and careful design. This makes EGaIn ideal for use in flexible and stretchable electronics, where it can be patterned into specific shapes to act as a sensitive strain sensor, opening up possibilities for its integration into wearable technologies.
