7:10am: Before making break­fast you run your forearm across an ultra­vi­olet reader on your wall to check your glu­cose levels. Your “nano-​​tattoo” shines back a reading that shows you are in the healthy blood-​​sugar range.

Heather Clark, inventor of nano-​​tattoos and an asso­ciate pro­fessor of phar­ma­ceu­tical sci­ences in North­eastern University’s Bouvé Col­lege of Health Sci­ences in Boston, explains that such tech­nology “could be very user friendly, because once the sensor ‘tattoo’ was inserted, it would be easy and pain­less to take a reading using just light through the skin.” Nano-​​tattoos are still a long way off but Clark esti­mates that, if they do become com­mer­cially avail­able, they would be very cheap.
