Wireless sensors that stick to the skin to track our health


Stanford engineers have developed a way to detect physiological signals emanating from the skin with sensors that stick like band-aids and beam wireless readings to a receiver clipped onto clothing.

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


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


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.

An implant that releases painkillers inside the body


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


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


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.
