4D Printing: 3-D printed structures “remember” their shapes

Engineers from MIT and Singapore University of Technology and Design (SUTD) are using light to print three-dimensional structures that “remember” their original shapes. Even after being stretched, twisted, and bent at extreme angles, the structures sprang back to their original forms within seconds of being heated to a certain temperature “sweet spot.” The team printed … Continue reading “4D Printing: 3-D printed structures “remember” their shapes”

Sponge creates Steam using ambient sunlight without requiring Mirrors or Lenses

Harvesting solar energy as heat has many applications, such as power generation, residential water heating, desalination, distillation and wastewater treatment. However, the solar flux is diffuse, and often requires optical concentration, a costly component, to generate the high temperatures needed for some of these applications. MIT engineers have invented a bubble-wrapped, sponge-like device that soaks … Continue reading “Sponge creates Steam using ambient sunlight without requiring Mirrors or Lenses”

MIT’s Programmable Network Routers enable Flexible Traffic Management, without sacrificing Speed

Like all data networks, the networks that connect servers in giant server farms, or servers and workstations in large organizations, are prone to congestion. When network traffic is heavy, packets of data can get backed up at network routers or dropped altogether. Also like all data networks, big private networks have control algorithms for managing … Continue reading “MIT’s Programmable Network Routers enable Flexible Traffic Management, without sacrificing Speed”

Interscatter Communication enables Smart Contact Lenses and Credit Cards that ‘talk’ Wi-Fi

University of Washington researchers have introduced a new way of communicating that allows devices such as brain implants, contact lenses, credit cards and smaller wearable electronics to talk to everyday devices such as smartphones and watches. This new “interscatter communication” works by converting Bluetooth signals into Wi-Fi transmissions over the air. Using only reflections, an … Continue reading “Interscatter Communication enables Smart Contact Lenses and Credit Cards that ‘talk’ Wi-Fi”

Intel Unveils Project Alloy, a Cord-less VR Headset providing “Merged Reality”

During the opening keynote of the Intel Developer Forum (IDF) in San Francisco, Intel CEO Brian Krzanich unveiled Project Alloy, an all-in-one virtual reality solution leveraging Intel RealSense technology. The computing power is located in the Alloy Head-Mounted Device (HMD), which allows the user to experience VR untethered. That means you can “cut the VR … Continue reading “Intel Unveils Project Alloy, a Cord-less VR Headset providing “Merged Reality””
