Atif Shamin a PhD student at Carleton University in Canada invented a 'transmitter system on-package' that significantly extends the battery life of mobile devices. He targeted the connection between the circuit board and the antenna. Instead of wire, he designed a high frequency micro-transmitter and receiver, avoiding the usual loss of power pumping bits through a wire. He has reached a breakthrough in the energy efficiency of mobile devices. He created a module that replaces all of the wires connecting a phone's electrical circuits and the antennae, making them communicate wirelessly. This makes the device's efficiency 12 times over, drastically improving battery life.
