Faster lasers for better memory To visualize in four dimensions the changing atomic configurations of materials undergoing phase changes — which happens when data is recorded on DVDs and Blu-ray disks — Caltech researchers have adopted a novel technique called ultrafast electron crystallography (UEC) that uses ultrafast laser pulses that speed up the data recording process. Interestingl... » read more

Power/Performance Bits: June 30

Tiny, solar-powered sensors Last week, at the Symposia on VLSI Technology and Circuits, MIT researchers presented a new power converter chip that can harvest more than 80 percent of the energy trickling into it, even at the extremely low power levels characteristic of tiny solar cells. Previous ultralow-power converters that used the same approach had efficiencies of only 40 or 50 percent. ... » read more

Implantable drug-delivery chip An implantable, microchip-based device developed by MIT spinout Microchips Biotech may soon replace the injections and pills now needed to treat chronic diseases. The company partnered with Teva Pharmaceutical to commercialize its wirelessly controlled, implantable, microchip-based devices that store and release drugs inside the body over many years.

Magnifying motions indiscernible to the naked eye For several years now, the research groups of MIT professors of computer science and engineering William Freeman and Frédo Durand have been investigating techniques for amplifying movements captured by video but indiscernible to the human eye. Versions of their algorithms can make the human pulse visible and even recover intelligible speech fr... » read more

Origami robot At the recent International Conference on Robotics and Automation, MIT researchers presented a printable origami robot that folds itself up from a flat sheet of plastic when heated and measures about a centimeter from front to back. The robot weighs just a third of a gram, and can swim, climb an incline, traverse rough terrain, and carry a load twice its weight. Other than the... » read more

Optical constraints Stanford University researchers have discovered strong constraints to optical data transmission but hope it can guide future research in this area. As a reminder, optics, a form of data transmission that utilizes beams of light, has the promise to outperform the beams of electrons that drive computers or smartphones. And as engineers have long looked for a way to miniatu... » read more

Asynchronous Design: Is It Time Yet?
By Barry Pangrle - 05 Jun, 2015 - Comments: 0

Non-mainstream technologies can offer advantages over more commonly used approaches, but usually at some additional cost (otherwise they’d probably be mainstream). The additional cost could be in design time, area, testability or whatever, and it might even be only a temporary disadvantage. If comparable time and energy were invested in the new technology, perhaps the additional costs would d... » read more

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.

Microfluidic cell-squeezing MIT researchers have shown it is possible to use a microfluidic cell-squeezing device to introduce specific antigens inside the immune system’s B cells, providing a new approach to developing and implementing antigen-presenting cell vaccines. These types of vaccines are created by reprogramming a patient’s own immune cells to fight invaders, and are believed ... » read more

Self-steering bullets DARPA has completed the development of a self-steering bullet that increases the hit rate for long-distance shots. The effort, dubbed the Extreme Accuracy Tasked Ordnance (EXACTO) program, is aimed for military snipers. The technology combines a maneuverable bullet and a real-time guidance system to track and deliver the projectile to the target, according to DARPA. It... » read more
