The latest technology imprints text messages on your skin so in order to read the message without needing to get your cell phone out there.

This concept, called SkinDisplay, employs advanced piezoelectric technology, which stiffens materials using electricity. In this way, you could press your finger down on the back of your phone and the raised letters would form an imprint that allows you to read your texts in a more tactful manner! This technology also has rather obvious applications to Braille reading systems for blind people.
