Those swag temporay tattoos that you pick up at beer festivals or brewery taprooms might have an additional use in the future if scientists at UC San Diego can make their new technology affordable enough for single use.
The research is part of developing a more reliable and quick measurement of blood alcohol levels. Their temporary tattoo includes microscopic sensors that are coated with a substance that stimulates sweating. Once the full cycle is run, the results are sent wirelessly to a smart phone.
