Simple self-charging battery offers power solutions for devices

A new type of battery combines negative capacitance and negative resistance within the same cell, allowing the cell to self-charge without losing energy, which has important implications for long-term storage and improved ...

Highly sensitive sensors show promise in enhancing human touch

People rely on a highly tuned sense of touch to manipulate objects, but injuries to the skin and the simple act of wearing gloves can impair this ability. Surgeons, for example, find that gloves decrease their ability to ...

Tiny magnetic structures enhance medical science

Small magnetic objects, which have been used successfully in technological applications such as data storage, are showing promise in the biomedical field. Magnetic nanostructures have interesting properties that enhance novel ...

Brain-inspired computing for a post-Moore's Law era

Since the invention of the transistor in 1947, computing development has seen a consistent doubling of the number of transistors that can fit on a chip. But that trend, known as Moore's Law, may reach its limit as components ...

3-D printing, bioinks create implantable blood vessels

A biomimetic blood vessel was fabricated using a modified 3-D cell printing technique and bioinks, which were formulated from smooth muscle cells from a human aorta and endothelial cells from an umbilical vein. The result ...
