Scientists at the Ulsan National Institute of Science and Technology in South Korea have developed small, flexible environmental sensors that can be applied to most any surface, according to Phys.org.
The sensors are fashioned out of carbon-based components and can be made in a single process. The sheet-thin sensors integrate transistors, electrodes and interconnects.
Creators of the environmental sensors say that they can attach to a wide range of surfaces, including paper and clothes. They can also stick to plants, small insects or human skin.
