Artificial muscles give soft robots superpowers

Soft robotics has made leaps and bounds over the last decade as researchers around the world have experimented with different materials and designs to allow once rigid, jerky machines to bend and flex in ways that mimic and can interact more naturally with living organisms. However, increased flexibility and dexterity has a trade-off of reduced strength, as softer materials are generally not as strong or resilient as inflexible ones, which limits their use.

Soft robotic actuator for one-sided heart failure

Soft robotic actuators, which are pneumatic artificial muscles designed and programmed to perform lifelike motions, have recently emerged as an attractive alternative to more rigid components that have conventionally been used in biomedical devices. In fact, earlier this year, a Boston Children's Hospital team revealed a proof-of-concept soft robotic sleeve that could support the function of a failing heart.

Artificial pancreas performs well in clinical trial

During more than 60,000 hours of combined use of a novel artificial pancreas system, participants in a 12-week, multi-site clinical trial showed significant improvements in two key measures of well-being in people living with type 1 diabetes.

Shedding light on how humans walk...with robots

With the recent boom of the robotic exoskeleton industry, more and more patients are being strapped into machines that apply forces to their legs as they walk, gently prodding them to modify their movements by lengthening their strides, straightening their hips, and bending their knees. But, are all patients benefiting from this kind of treatment?

Long-lasting flow battery could run for more than a decade

Researchers have developed a new flow battery that stores energy in organic molecules dissolved in neutral pH water. This new chemistry allows for a non-toxic, non-corrosive battery with an exceptionally long lifetime and offers the potential to significantly decrease the costs of production.

Metabolic energy savings from wearable gait-improving robot

By removing the actuation, electronics and battery units, leaving only the exosuit's light wearable textiles and pulling cables, the researchers were able to calculate the impact on the wearers' joints.
