Generating power via piezoelectrical processes has always been limited by the size of the device and the frequency generated, but researchers at Singapore’s Agency for Science, Technology and Research (A*STAR) claim to have found a way to harvest enough power from low-frequency vibrations to power small electronics.
Google Glass has been making the news for awhile now thanks to everything from technical innovation to fashion critiques to privacy concerns. Now Google is trying its hand at electronic contact lenses. Continue reading
New “stretchy” sensors built on nanowire conductors could potentially be embedded in clothing, or on human skin and other surfaces to track strain and pressure, or provide touch-based functionality in new form factors. Continue reading
It’s January, and you’ve got your thermostat set to help fight off the cold. Then you start cooking a four-course meal in the kitchen, and the combination of the furnace and your oven have you peeling off your cardigan and wiping sweat from your brow. What to do? How about installing a smart thermostat sensor that can adjust the temperature based on the room you happen to be standing in? Allure Energy has expanded its “smart home” technology to include a sensor that combines near field communication (NFC) for Android devices and Bluetooth Low Energy (BLE) for Apple’s iBeacon Technology in a single form factor.
Wireless sensors are becoming more pervasive as we move toward the “Internet of Things” that futurists have been telling us is on the horizon. But for these sensors to work, they have to have power. In some cases, the sensors can piggyback on items that are already hooked up to the grid (like refrigerators). In others, though, the sensors either need battery power or some other form of energy, and that has traditionally mean that the sensors themselves have to be large enough to accommodate a power source. Those size considerations, in turn, limit design possibilities. Continue reading
