Abstract
“What if electronics devices are printed using an inkjet printer even at home?”“What if those devices no longer need a battery?”I will introduce two enabling technologies for the Internet of Things concept.1. Instant Inkjet Circuits:A low cost, fast and accessible technology to support the rapid prototyping of electronicdevices. We demonstrated that “sintering-free” silver nano particle ink with a commodity inkjetprinter can be used to fabricate printed circuit board and high-frequency applications such asantennas and sensors. The technology is now commercialized by AgIC, Inc.2. Wireless Power:Although large amounts of data can be exchanged over a wireless communication link,mobile devices are still tethered by power cables. We are trying to solve this problem by twodifferent approaches: energy harvesting. A simple circuitry comprised of diodes and capacitorcan convert ambient radio signals into DC current. Our research revealed the signals from TVtower located 6.5km apart could be used to feed 100 microwatts to power microcontrollers.
