Metal-silicone microstructures could enable new flexible optical and electrical devices: Laser-based method creates force-sensitive, flexible microstructures that conduct electricity
For the first time, researchers have used a single-step, laser-based method to produce small, precise hybrid microstructures of silver and flexible silicone. This innovative laser processing technology could one day enable smart factories that use one production line to mass-produce customized devices combining soft materials such as engineered tissue with hard materials that add functions such as glucose sensing.

The metal component of the microstructures renders them electrically conductive while the elastic silicone contributes flexibility. This unique combination of properties makes the structures sensitive to mechanical force and could be useful for making new types of optical and electrical devices.
"These types of microstructures could possibly be used to measure very small movements or changes, such as a slight movement from an insect's body or the subtle expression produced by a human facial muscle," said research team leader Mitsuhiro Terakawa from Keio University, Japan. "This information could be used to create perfect computer-generated versions of these movements."
