What the researchers found is they could apply the right amount of voltage on a layer of metal going around a core of piezoelectric film to change its permeability. As the film changes permeability, its electrons can move at different frequencies.
Ng said the research means future inductors can be used to improve radio signal performance, which could eliminate the number of modules needed in a smartphone, with the potential to reduce the cost of materials.
Intel and Texas Instruments cooperated in the work, and the new inductor technology will be available for further industrial development by the middle of next year, followed by use in consumer applications by as earlier as late 2014.
