Sensors woven into a shirt can monitor vital signs
Sensors woven into a shirt can monitor vital signs
MIT researchers have developed a way to incorporate electronic sensors into stretchy fabrics, allowing them to create shirts or other garments that could be used to monitor vital signs such as temperature, respiration, and heart rate. The sensor-embedded garments, which are machine washable, can be customized to fit close to the body of the person wearing them.

Photonic microwave generation using on-chip optical frequency combs
Photonic microwave generation using on-chip optical frequency combs
Using integrated photonic chips fabricated at EPFL, scientists have demonstrated laser-based microwave generators. These microwave signals, as well as their optical carriers, could be used in radars, satellite communications and future 5G wireless networks. In our information society, the synthesis, distribution, and processing of radio and microwave signals are ubiquitous in wireless networks, telecommunications, and radars.

Fine-Tuning Magnetic Spin for Faster, Smaller Memory Devices
Fine-Tuning Magnetic Spin for Faster, Smaller Memory Devices
Unlike the magnetic materials used to make a typical memory device, antiferromagnets won't stick to your fridge. That's because the magnetic spins in antiferromagnets are oppositely aligned and cancel each other out. Scientists have long theorized that antiferromagnets have potential as materials for ultrafast stable memories.

Energy-harvesting design aims to turn Wi-Fi signals into usable power
Energy-harvesting design aims to turn Wi-Fi signals into usable power
Device for harnessing terahertz radiation might enable self-powering implants, cellphones, other portable electronics. Any device that sends out a Wi-Fi signal also emits terahertz waves -electromagnetic waves with a frequency somewhere between microwaves and infrared light. These high-frequency radiation waves, known as "T-rays," are also produced by almost anything that registers a temperature, including our own bodies and the inanimate objects around us.

A nanoscale device that can see through walls
A nanoscale device that can see through walls
Researchers at EPFL have developed a nanodevice that operates more than 10 times faster than today's fastest transistors, and about 100 times faster than the transistors you have on your computers. This new device enables the generation of high-power terahertz waves. These waves, which are notoriously difficult to produce, are useful in a rich variety of applications ranging from imaging and sensing to high-speed wireless communications.

Novel method for easier scaling of quantum devices
Novel method for easier scaling of quantum devices
System "recruits" defects that usually cause disruptions, using them to instead carry out quantum operations. In an advance that may help researchers scale up quantum devices, an MIT team has developed a method to "recruit" neighboring quantum bits made of nanoscale defects in diamond, so that instead of causing disruptions they help carry out quantum operations.

Integrating electronics onto physical prototypes
Integrating electronics onto physical prototypes
In place of flat "breadboards," 3D-printed CurveBoards enable easier testing of circuit design on electronics products. The aim is to provide a faster, easier way to test circuit functions and user interactions with products such as smart devices and flexible electronics. Breadboards are rectangular boards with arrays of pinholes drilled into the surface.

Quakes, dust devils and midnight magnetic pulses: findings from a year on Mars
InSight's Imperial-designed instrument has revealed that Mars trembles more often, but also more mildly, than expected. Detecting hundreds of marsquakes on a planet 140 million miles from Earth, using sensors developed in the UK, is an important achievement. Amanda Solloway UK Science Minister An international team of scientists led by NASA created Mars InSight , the first mission to study the deep interior of Mars , to generate unprecedented data about the planet's inner structure.

Time-resolved measurement in a memory device
Time-resolved measurement in a memory device
Researchers at ETH have measured the timing of single writing events in a novel magnetic memory device with a resolution of less than 100 picoseconds. Their results are relevant for the next generation of main memories based on magnetism. At the Department for Materials of the ETH in Zurich, Pietro Gambardella and his collaborators investigate tomorrow's memory devices.

Engineers mix and match materials to make new stretchy electronics
Engineers mix and match materials to make new stretchy electronics
Next-generation devices made with new "peel and stack" method may include electronic chips worn on the skin. Because computer chips are rigid, the electronic devices that they power, such as our smartphones, laptops, watches, and televisions, are similarly inflexible. Now a process developed by MIT engineers may be the key to manufacturing flexible electronics with multiple functionalities in a cost-effective way.
