In recent years, the hot application for quantum dots has been as a replacement for light-emitting diodes (LEDs) as a backlight source for liquid crystal displays. But now, an international team of researchers has produced engineered nanorods that each feature a quantum dot capable of emitting and absorbing visible light. With this advance, quantum dots could someday yield mobile phones that can “see” without the need of a camera lens or communicate with each other using Light Fidelity (Li-Fi) technology.
A recent opinion piece about wearable tech for infants pulls no punches: “There is no evidence that consumer infant physiologic monitors are life-saving, and there is potential for harm if parents choose to use them.” That wasn’t just any random person’s judgement. The article was published in the Journal of the American Medical Association and was authored by two pediatricians and an expert from the ECRI Institute, a nonprofit organization dedicated to the rigorous evaluation of medical procedures and devices.
The 252-electrode device could help doctors pinpoint the locations of electrical malfunctions in the heart that cause irregular heartbeats.
The tiny CMOS-based transmitter can send data packets wirelessly at rates as high as 105 gigabits per second.
University of Michigan micro-mote computers—tiny, energy efficient computing sensors that can do analysis on board—aim to make the Internet of Things smarter without consuming more power.
