Lightweight exosuit made from textiles

Between walking at a leisurely pace and running for your life, human gaits can cover a wide range of speeds. Typically, we choose the gait that allows us to consume the least amount of energy at a given speed. For example, at low speeds, the metabolic rate of walking is lower than that of running in a slow jog; at high speeds, the metabolic rate of running is lower than that of speed walking.

Wearable motion sensors could save unborn babies

16.08.2019

The thump, thump of a baby's heartbeat is a milestone in any pregnancy. Now, researchers at Stevens Institute of Technology have developed a technique that could allow expectant parents to hear their baby's heartbeat continuously at home with a non-invasive and safe device that is potentially more accurate than any fetal heartrate monitor currently available in the market.

Materials: A revolutionary new way for metals to be malleable

15.08.2019

For nearly 100 years, scientists thought they understood everything there was to know about how metals bend. Materials science and engineering researchers at the University of Wisconsin-Madison have demonstrated that the rules of metal-bending are not so hard and fast after all.

Electronics: turning away bacteria with your clothes

14.08.2019

New rainproof, stainproof technology turns clothing into self-powered remotes. A new addition to your wardrobe may soon help you turn on the lights and music - while also keeping you fresh, dry, fashionable, clean and safe from the latest virus that's going around.

An implant that releases painkillers inside the body

13.08.2019

Researchers in EPFL's Microsystems Laboratory are now working on a biodegradable implant that would release a local anesthetic on-demand over several days. Not only would this implant reduce patients' post-op discomfort, but there would be no need for further surgery to remove it.

Liquid biopsy chip snares circulating tumor cells

09.08.2019

WPI researcher's new liquid biopsy chip, made of carbon nanotubes, snares circulating cancer cells with far greater sensitivity and could make it possible to detect early-stage tumors, predict the course of a cancer, and monitor the effects of therapy.

Microtechnology: little robots to treat tumors

08.08.2019

Targeting medical treatment is a practice as old as medicine itself. But what is inside the body, is not so easy to reach. In such cases, a treatment like surgery might be called for. Researchers in Caltech's Division of Engineering and Applied Science are working on microrobots that can deliver drugs to specific spots inside the body while being monitored and controlled from outside the body.

FRESH 3D printing rebuilds functional components of human heart

07.08.2019

A team of researchers from Carnegie Mellon University has published a paper in Science that details a new technique allowing anyone to 3D bioprint tissue scaffolds out of collagen, the major structural protein in the human body. This first-of-its-kind method brings the field of tissue engineering one step closer to being able to 3D print a full-sized, adult human heart.

3D-printed pill samples aid diagnosis and treatment

06.08.2019

The pill is the first known working device capable of non-invasively and accurately assessing the profile of bacterial species inhabiting any stage of the gastrointestinal tract. The ability to profile bacterial species inhabiting the gut could have important implications for conditions that affect and are affected by the intestinal microbiome.

Tiny vibration-powered robots

02.08.2019

Researchers have created a new type of tiny 3D-printed robot that moves by harnessing vibration from piezoelectric actuators, ultrasound sources or even tiny speakers. Swarms of these “micro-bristle-bots” might work together to sense environmental changes, move materials – or perhaps one day repair injuries inside the human body.
