Sensing skin spots cracks in structures

Researchers have developed a multi-layered “sensing skin” to detect corrosive or otherwise harmful substances in structures. The skin can also detect cracks and other structural flaws that are invisible to the naked eye.

An electric car currently relies on a complex interplay of both batteries and supercapacitors to provide the energy it needs to go places. But chemists are developing a new material that could change that.
