Antenna on a Chip Could Drastically Improve the Internet of Things

Apr-24-15 Based on new understandings in electromagnetism, researchers have created tiny wireless antennas that could one day be built onto computer chips.

Developed by a team from Cambridge, the antennas are made from piezoelectric thin film materials that will vibrate under voltage. During exploration into the materials, the team discovered that they also become effective antennas when they are excited asymmetrically. This asymmetric stimulation causes the material's energy field to change and generate electromagnetic radiation, which in turn releases electromagnetic waves.

The technology could have particular applications in the development of the Internet of Things, where a tiny antenna on an electric chip could drastically improve connectivity.
