Scientists form Superior Scientific Research Council (CSIC) from Spain, have developed batteries that are microfluid combustible in paper and they are like small devices that can diagnose like lateral flow bands, as you find in pregnancy tests, or glucose tests, they work without outside batteries.
Flow lateral bands have been used in the diagnosis field because they are cheap, lightweight, mobility, and they can bring us quickly answers and results are easy to read. Sometimes, these devices need a battery lector to evaluate the result. Although, they solve how to avoid external battery with the approach of a solution developed by the collaboration of two institutions: Microelectronic Institute of Barcelona, in association with Catalysis and Petrochemistry (both associations belong to CSIC).They made up a battery with combustible that brings enough electrical power for feeding the optical sensors of an essay and they show the results without an external battery.
Paper is cheap, biodegradable, slim, flexible, and it can transport fluids by capillarity. Scientists know paper material characteristics and assign elements that react with a liquid sample in the paper– water in this specific case- , so they get the reaction and generate electricity to start up the diagnosis device.
The discovery opens the door to a new wage of chance, it finally depends on the application that can be done.
Now essays has been developed by using methanol as a combustible but scientist are working in the devise optimization, they want to get the mechanism could work with the energy of the molecules that are already in the biological liquids, they are glucose in the blood or urea in the urine.
The application of this discovery can be done in the biomedical field, but it can be also extended to other disciplines as environmental, veterinary, agriculture, and safety, furthermore.
Researchers go on towards the integration of the combustible battery with the electronic organic technology. In this way all the necessary elements: sensors, energy source, electronic, and scream can be produced in a single process.
