Irish scientists have recently discovered how to produce electricity from human tears. It is very obvious to get tears when we cry and even when we laugh. So far we have known that tears are salty. But the shocking matter that hidden in the tears is it can produce electricity. Till now we have look at tears as worthless drops. But this research is an eye opener for everyone to know the value of tears. Now tears are most valuable drops that too in the form of electricity. We can generate electricity by applying a pressure on the protein that found in tears, Irish scientists said.
Generating Electricity out of Tears:
The researchers from the Bernal Institute, University of Limerick (UL), Ireland, observed the crystals of lysozyme protein in the tears. This protein is abundant in the tears. Scientists said we can generate electricity from tears by applying pressure on the lysozyme protein. Not only in tears this modern protein is also present in egg whites of birds. It seems that egg also contains electricity.
Even milk also contains lysozyme crystals and these crystals belongs to protein category. The research team has observed the presence of lysozyme in the egg whites of birds, as well as in the tears, saliva and milk of mammals. Their report was published on October 2 in the journal, Applied Physics Letters.
Scientists are saying that milk has the quality to convert the Mechanical energy into Electrical energy. This process is known as Piezoelectricity. Piezoelectricity is the property that the ability to generate electricity by applying pressure. The capacity to generate electricity from this particular protein has not thus far been explored. Because it is a biological material it is non-toxic. Prof Tewfik Soulimane we are the first to use these crystals to show the evidence of piezoelectricity”.
