Concordia researchers have developed a new 3D-printing technique that uses sound waves to directly print tiny structures onto soft polymers like silicone with far greater precision than before. The approach, called proximal sound printing, opens new possibilities for manufacturing microscale devices used in health care, environmental monitoring and advanced sensors.... Read more

Measuring human movement with tracking devices on looser clothing is more accurate than on tight body suits or straps. This discovery by scientists at King's College London could mark a potential breakthrough for a range of technologies, including improving accuracy of personal health devices, such as Fitbits and smart watches,...

Drawing on an extensive survey of emerging battery chemistries and design innovations, researchers at the University of Sharjah are pointing to transformative technologies poised to meet the escalating energy demands of an increasingly electrified world.... Read more

In a long-running collaboration with GE Aerospace, researchers at the University of Melbourne in Australia have been steadily working to improve the performance of high-pressure turbine (HPT) engines through computer simulations on leadership-class computing systems. These turbines are the heart of jet engines used in many commercial and military aircraft.... Read more

A male fruit fly in a laboratory chamber extends his wings and vibrates them to produce his species' version of a love song. A female fly stays nearby listening. Suddenly, a green light flashes across the chamber for a fraction of a second. The male's song cuts off mid-note and... Read more

3D bioprinting, in which living tissues are printed with cells mixed into soft hydrogels, or "bio-inks," is widely used in the field of bioengineering for modeling or replacing the tissues in our bodies. The print quality and reproducibility of tissues, however, can face challenges. One of the most significant challenges... Read more

Much like baking the perfect cake involves following a list of ingredients and instructions, manufacturing energetic materials—explosives, pyrotechnics and propellants—requires precise formulations, conditions and procedures to ensure they are safe and perform as intended.... Read more

A little-known fact: In the year 1900, electric cars outnumbered gas-powered ones on the American road. The lead-acid auto battery of the time, courtesy of Thomas Edison, was expensive and had a range of only about 30 miles. Seeking to improve on this, Edison believed the nickel-iron battery was the...

An international research team has demonstrated a new approach to 4D-printed shape-morphing implants that opens the door to increasingly personalized health care. The findings, outlined in the journal Additive Manufacturing, highlight how material degradation can be used to trigger controlled shape change of implanted material.... Read more

It's a typical workday and you sign onto your computer. Unbeknownst to you, a high-frequency sensing system embedded in your work device is now tracking your heart rate, allowing your employer to monitor your breaks, engagement, and stress levels and infer alertness. It sounds like a dystopian scenario, but some... Read more

Soft robots made out of flexible, biocompatible materials are in high demand in industries from health care to manufacturing, but precisely designing and controlling such robots for specific purposes is a perennial challenge. What if you could 3D print a soft robot with predictable shape-morphing capabilities already built in? Harvard... Read more

Sensors small enough to disappear into the body, microrobots that move without wires, and smart systems hidden inside everyday materials—all require a battery to function. As electronics shrink towards the micrometer scale, conventional batteries become bulky, impractical, or impossible to integrate into these tiny devices.... Read more

A research team has used advanced 3D printing techniques to develop low-temperature, "sinterless" silica glass. They converted 3D-printed objects into silica glass structures at significantly lower temperatures than traditional sintering, offering a promising route for efficient and precise glass manufacturing. Their research is published in the journal Polymers.... Read more

Researchers have fabricated a hair-thin microphone made entirely of silica fiber that can detect a large range of ultrasound frequencies beyond the reach of the human ear. Able to withstand temperatures up to 1,000°C, the device could eventually be used inside high-voltage transformers to detect early signs of failure before... Read more

Dynamic digital product passports—real-time, intelligent digital records that capture the true condition of perishable goods such as food and drink throughout their life cycle—could dramatically cut waste and improve safety, thanks to a new framework jointly developed by researchers at the University of Surrey and King's College London....
