Graphene Coated Liquid Metal Droplet‐Enabled Dual‐Axis Integrated Accelerometer (Adv. Mater. Technol. 1/2023)

Inertial Sensors In article number 2201094, Wedyan Babatain, Muhammad Mustafa Hussain, and co-workers present a liquid metal droplet-based robust dual-axis accelerometer. The liquid metal droplet is coated with graphene flake and confined inside a pyramid-shaped cavity patterned with laser-induced graphene (LIG) interdigitated electrode to realize a highly mobile mass and sensitive sensor. The device's utility is demonstrated for real-time- monitoring of hand motion and precise control of a virtual pong game.
