Irish Scientists Discover Method to Produce Electricity from Tears

A team of scientists at University of Limerick has discovered that applying pressure to a protein found in egg whites and tears can generate electricity. The researchers from the Bernal Institute observed that crystals of lysozyme, a model protein that is abundant in egg whites of birds as well as in the tears, saliva and milk of mammals can generate electricity when pressed. Their report was published on October 2 in the journal, Applied Physics Letters.
