TEENY-TINY BLUETOOTH TRANSMITTER RUNS ON LESS THAN 1 MW

Bluetooth Low Energy data packets can now be sent by millimeter-size IoT motes. By Samuel K. Moore @ spectrum.ieee.org Engineers at the University of Michigan have now built the first millimeter-scale stand-alone device that speaks BLE. Consuming just 0.6 milliwatts during transmission, it would broadcast for 11 years using a typical 5.8-millimeter coin battery. Such …

Researchers Of RMIT University Develops Swalloable Gas Sensors That Can Improve Your Diet

Researchers led by Kourosh Kalantar-Zadeh, at RMIT University in Melbourne, Australia have developed the first intestinal gas-diagnosing pill to be tested in human. During the study, which was published on January 8 in Nature Electronics, the swallowable gas sensors were tested in seven healthy participants who ate low and high-fiber diets. This ‘smart’ capsule is capable of measuring levels of Oxygen, …
