Calling all couch potatoes: this finger wrap can let you power electronics while you sleep

A new wearable device turns the touch of a finger into a source of power for small electronics and sensors. Engineers at the University of California San Diego developed a thin, flexible strip that can be worn on a fingertip and generate small amounts of electricity when a person’s finger sweats or presses on it. What’s special about this sweat-fueled device is that it generates power even while the wearer is asleep or sitting still.

Nanotech scientists create world’s smallest origami bird

Cornell University researchers have created micron-sized shape memory actuators that enable atomically thin two-dimensional materials to fold themselves into 3D configurations. All they require is a quick jolt of voltage. And once the material is bent, it holds its shape – even after the voltage is removed.

UCI-led team creates new ultralightweight, crush-resistant tensegrity metamaterials

Irvine, Calif., March 11, 2021 – Catastrophic collapse of materials and structures is the inevitable consequence of a chain reaction of locally confined damage – from solid ceramics that snap after the development of a small crack to metal space trusses that give way after the warping of a single strut. In a study published this week in Advanced Materials, engineers at the University of California, Irvine and the Georgia Institute of Technology describe the creation of a new class of mechanical metamaterials that delocalize deformations to prevent failure.

Twistoptics—A New Way to Control Optical Nonlinearity

Columbia Engineering researchers report that they developed a new, efficient way to modulate and enhance an important type of nonlinear optical process: optical second harmonic generation—where two input photons are combined in the material to produce one photon with twice the energy—from hexagonal boron nitride through micromechanical rotation and multilayer stacking. Their work is the first to exploit the dynamically tunable symmetry of 2D materials for nonlinear optical applications.

Researchers watch anti-cancer drug release from DNA nanostructures in real time

A team of researchers from Finland and Germany have found a way to study the endonuclease-driven digestion of drug-loaded DNA nanostructures in real time. As the team investigated the binding of anti-cancer drug doxorubicin (Dox) to the DNA structures in great detail, they discovered that the majority of previous studies have vastly overestimated the Dox loading capacity of DNA origami.
