"If a two-year-old child has to go through open heart surgery every seven or eight years that could translate into approximately ten surgeries in his or her life span to implant new pacemakers," said professor Salehian of Waterloo's Department of Mechanical and Mechatronics Engineering. "The number may be reduced noticeably by harvesting energy through vibra- tions and human motion to prolong the battery life." Salehian's team, which includes graduate and undergraduate me- chanical and mechatronics en- gineering students, completed a prototype for the new hybrid technology in August that has also shown potential for various wire- less sensing applications. There is strong demand for more energy-efficiency units in today's technology thanks to the increased use of electronic devices ranging from mobile phones and wireless sensors to medical implants. Self- sustained systems that can harvest different forms of ambient energy have the potential to lower costs and the need for regular battery replacements in devices such as pacemakers. While other researchers have un- dertaken similar work, the majority have developed devices designed for narrower ranges of vibration frequencies. For example, if an individual is moving at a certain pace, the device produces power but as soon as the rate of motion is changed or the frequencies are slightly different, the amount of power reduces significantly. "The prototype we've developed uses a combination of smart ma- terials so the amount of harvested energy can be increased at a wider range of frequencies," said Sale- hian. "This research could also be used to power wireless sensors that help detect cracks and damage to buildings." Salehian is currently working to establish industrial partnerships with companies in North America.

Professor Armaghan Salehian's research group has developed wideband hybrid energy harvest- ers that use different types of smart materials to convert ambient vibrations into electricity. Used in pacemakers, the technology could trends in sample Preparation Perspective on today's needs and tomorrow's opportunities Page 7 revolutionizing fresh water production Page 13 Professor Armaghan Salehian.
