A team of researchers has discovered that crying can generate electricity.
They discovered that applying pressure to a protein found in tears as well as egg whites can generate electricity.
The discovery could have wide reaching applications in the field of flexible electronics for biomedical devices – for example controlling the release of drugs in the body.
The ability to generate electricity by applying pressure to a material is called piezoelectricity.
It is a property of materials such as quartz, which can convert mechanical energy into electrical energy, and vice versa. Read more
