Researchers from the University of Waterloo have created a compact, portable generator to meet the growing demand for sustainable, clean energy. This technology is also scalable for use in larger machines. The research was published in the journal Nature communication.
The new generator contains materials that are flexible, energy efficient and relatively cheaper. Image credits: University of Waterloo.
This groundbreaking technology, which captures electricity from vibrations or small body movements, could allow devices to charge while in use, such as powering a laptop while typing or charging a smartphone during a morning run.
This is a real game changer. We’ve created the first device of its kind that can power electronics at a low cost and with unprecedented efficiency.

The device uses the piezoelectric effect, which generates electrical energy when pressure is applied to materials such as crystals and certain ceramics. Piezoelectric materials are already used in various detection technologies, including sonar, ultrasound imaging and microwave devices.
These older materials are brittle, expensive and have a limited ability to generate electricity. The materials we made for the new generator are flexible, more energy efficient and cheaper.

In addition to Khan and Ban, the research team includes two other professors from the University of Waterloo, a professor from the University of Toronto, and their respective research groups.
The researchers have applied for a patent and are working with a Canadian company to commercialize their generator. They plan to use it in aviation to power aircraft systems that monitor the status of safety equipment.
