A team of researchers at Southeast University in China has developed a self-healing structural hydrogel with a wide variety of applications. It has been noted for several years that one area where humanoid robots are lacking is skin tone—most robots have a pasty white complexion, which is both disturbing and likely to lead to social problems once robots become mainstream. Most artificial skin is not able to heal itself, which means that robots need skin replacement if it gets damaged or accidentally colored in undesirable ways. There is also the issue of colors fading...

The ability to control the motion of soft robots, coupled with flexibility, gives them potential applications ranging from biomedical technologies to manufacturing processes. Researchers are interested in using magnetic fields to control the movement of these soft robots because it can be done remotely – the control can be exerted without physically connecting to the polymer – and because magnetic fields are easily obtained from permanent magnets and electromagnets.
A team of researchers has now found a way of embedding long chains of nanoscale magnetite particles in sheets of elastic polymer to form a magnetic polymer nanoco...
Read More>>Researchers have designed new multimaterial printheads that mix and print concentrated viscoelastic inks that allow for the simultaneous control of composition and geometry during printing. Using active mixing and fast-switching nozzles, these novel printheads change material composition on the fly and could pave the way for entirely 3D printed wearable devices, soft robots, and electronics.
To print a flexible device, including the electronics, a 3D printer must be able to seamlessly transition from a flexible material that moves with your joints for wearable applications, t...
