Subcutaneous medicine chip A biosensor chip developed at EPFL is capable of simultaneously monitoring the concentration of a number of molecules, such as glucose and cholesterol, and certain drugs. It’s only a centimeter long, placed under a patient’s skin, powered by a patch on the surface of the skin, and communicates with a mobile phone.

Approaching power/performance tradeoffs from an architectural perspective is essential given the complexities of today’s SoCs. And beyond some traditional techniques that I discussed in a recent article, Bernard Murphy, CTO at Atrenta mentioned that there is currently a lot of buzz about using non-Von Neumann architectures — especially for recognition functions (voice, image and text). ... » read more

Boosting silicon solar cells According to Stanford researchers, stacking crystalline perovskites onto a conventional silicon solar cell dramatically improves the overall efficiency of the cell. The researchers reminded that silicon solar cells dominate the world market, but the power conversion efficiency of silicon photovoltaics has been stuck at 25 percent for 15 years. One inexpensive wa... » read more

High rise chip For decades, the mantra of the semiconductor industry has been ‘smaller, faster, cheaper.’ Stanford researchers are also adding ‘taller’ to the mix, and describing how to build high-rise chips that promise to leapfrog the performance of the single-story logic and memory chips on today's circuit cards. Stanford researchers said their approach would end the ‘logjams�... » read more

Light in lieu of wires In a development that could eventually lead to computers that use optics rather than electricity to carry data, Stanford engineers have designed and built a prism-like device they call an ‘optical link’ that can split a beam of light into different colors and bend the light at right angles. The optical link is a tiny slice of silicon etched with a pattern that res... » read more

Sound power While medical researchers would like to plant tiny electronic devices deep inside our bodies to monitor biological processes and deliver pinpoint therapies or relieve pain, so far engineers have been unable to make such devices small and useful enough. Providing power to the implants has been one stumbling block, and the use of wires or batteries to deliver power make implants ... » read more

Safety first A technology designed for conventional lithium-ion batteries by Stanford University researchers warns the user before it overheats and bursts into flames. The goal was to create an early-warning system to saves lives and property, by detecting problems that occur during the normal operation of a battery, the researchers said. The technology does not apply to batteries damaged i... » read more

The Missing Link

What continues to fascinate me about the IoT opportunity is the explosion of creative ideas that are being imagined and developed to enable the next big thing. When I imagine the kind of connectivity and control that will need to happen between the Internet and ‘smart’ devices, these things obviously must be very inexpensive, super small, with the ability to harvest their own energy. ... » read more

Phosphorus: a promising semiconductor According to researchers at Rice University, defects damage the ideal properties of many 2D materials, like carbon-based graphene, but phosphorus just shrugs, making it a promising candidate for nano-electronic applications that require stable properties. The team analyzed the properties of elemental bonds between semiconducting phosphorus atoms in 2D s... » read more

First transistor-based flexible device with graphene A flexible display incorporating graphene in its pixels’ electronics has been successfully demonstrated by the Cambridge Graphene Centre and Plastic Logic, the first time graphene has been used in a transistor-based flexible device. The prototype is meant to be a first step towards the wider implementation of graphene and graphene-like ... » read more
