Scientists developed the world’s smallest battery, about the size of a grain of dust, inspired by the Swiss-Roll dessert.
The self-assembling battery was created by making a layer of electric conductors and electrodes into a tensioned water surface. When the individual layers are peeled off, they unleash the tension on the water surface. This allows the materials to snap back and roll around each other. Scientists call this activity the Swiss-Roll process.
While limited by its size, the team believes that the micro-batteries could eventually be used to power small sensors in the human body, called biosensors. It can power the world’s smallest computer chips for about 10 hours, which could open up many biosensors applications.
