Atif Shamim has built a prototype that extends the battery life of portable devices such as cell phones and PDAs by getting rid of all the wires used to connect the electronic circuits with the antenna. His invention involves a packaging technique to connect the antenna with the circuits via a wireless connection between a micro-antenna embedded within the circuits on the chip. He estimates the module consumes 12 times less power than the traditional, wired-transmitter module and being simpler in design, would lower the overall cost of any hand-held device.
The paper about the invention, co-authored by Muhammad Arsalan, MASc/04, PhD/09, and adviser Langis Roy, was named the best paper at the European Wireless Technology Conference in 2008. The Ottawa Centre for Research and Innovation honoured Shamim and Arsalan as student researchers of the year in 2008 for their work in the field of wireless biomedical sensors and in 2010 with the Student Entrepreneur of the Year Award. The researchers were awarded the ITAC Strategic Microelectronics Council Industrial Collaboration Award in 2007 for a wireless dosimeter project with potential for commercialization. Their dosimeter overcomes the limitations of current models that are too large or restricted by wires, or have low sensitivity to radiation or a short transmission range.
