Stability of gallium-based liquid metal (ongoing)
|Galinstan and other gallium alloys that are liquid at room temperature are used in a wide range of soft robot and soft sensor devices, typically at low currents and power dissipations. To achieve high-current liquid metal devices (e.g., electromagnetic devices), we must understand the ability of these metals to tolerate large currents.|
Modifying soft sensor properties through morphology
|Planar resistors and capacitors made from soft insulators like silicone elastomer and conformal conductors like liquid metals are can withstand large strain and deformation without damage. Precisely defining their sensing properties (sensitivity, range, etc.) is an ongoing challenge. This project investigated the change in these properties that was possible by increasing (fusible metal) or decreasing (voids) the stiffness around the sensor.
