3D printing of living cells
Using a new technique they call 'in-air microfluidics', scientists succeed in printing 3D structures with living cells. This special technique enable the fast and 'on-the-fly' production of micro building blocks that are viable and can be used for repairing damaged tissue, for example.
Rotational 3D printing technique yields high-performance composites
Nature has produced exquisite composite materials—wood, bone, teeth, and shells, for example—that combine light weight and density with desirable mechanical properties such as stiffness, strength and damage tolerance.
Millimeter-scale robot opens new avenues for microsurgery
The milliDelta design incorporates a composite laminate structure with embedded flexural joints that approximate the more complicated joints found in large scale Delta robots.
Molecular Robotics capitalizes on recent explosion of technologies
Collaborations between nanotechnologists, synthetic biologists, and computer scientists create nanoscale tools that could revolutionize fields from cancer diagnostics to materials science.
Engineers program tiny robots to move, think like insects
While engineers have had success building tiny, insect-like robots, programming them to behave autonomously like real insects continues to present technical challenges.
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.
Synthetic circuits can harvest light energy
Novel structures made with DNA scaffolds could be used to create solar-powered materials.
Hybrid 3-D printing method for flexible electronics
A collaboration between scientists has resulted in a new method for digital design and printing of stretchable, flexible electronics. The process, called Hybrid 3-D printing, uses additive manufacturing to integrate soft, conductive inks with a material substrate to create stretchable, wearable electronic devices.
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.
