Smart droplets: Elevating tiny tech with a liquid metal signal-switching mechanism

A new methodology developed by scientists from Japan allows for the precise activation of integrated sensors by manipulating the droplets’ locations, thus detecting capacitance changes to estimate their positions without the need for visual confirmation. Such a strategy is invaluable in scenarios such as internal body examinations, where direct visibility is obstructed, where it outperforms conventional techniques by ensuring meticulous control over the droplets’ maneuvers.
