University of Tokyo researchers have developed a plastic pad that allows electronic devices placed on it to communicate with each other. This communications sheet could provide a more secure and lower-energy alternative to short-range wireless communications, such as Bluetooth.
“The first application might be an ‘intelligent table’ ” that would allow a few devices to communicate with each other without the need to wire them together, says Takao Someya, professor of engineering at the University of Tokyo. Someya says that the team’s long-term goal is to develop a system that connects thousands of devices, as might one day be required. The amount of energy needed to wirelessly connect such an array of devices “would be huge,” he says, and wiring them all together would be cumbersome. Someya’s approach uses a combination of extremely short-range wireless communications and wires to provide a low-energy alternative. more>>>
