Instead of sitting in a tattoo chair for hours enduring painful punctures, imagine getting tattooed by a skin patch containing microscopic needles. Researchers have developed low-cost, painless, and bloodless tattoos that can be self-administered and have many applications, from medical alerts to tracking neutered animals to cosmetics.

The pandemic gave people a lot more time with their dogs and cats, but return to the office has disrupted that connection. Pet cameras can help but are needed in every room and don't really tell owners what their furry friend has been up to without reviewing all footage. Now, researchers at the have created a new device that can put pet owners at ease.

A team of researchers has 3D printed a dual-phase, nanostructured high-entropy alloy that exceeds the strength and ductility of other state-of-the-art additively manufactured materials, which could lead to higher-performance components for applications in aerospace, medicine, energy and transportation.

Vascular diseases are public enemy number one: the leading killers worldwide, accounting for nearly a third of all human deaths on the planet. Continuous monitoring of hemodynamics - blood flow through the vascular system - can improve treatments and patient outcomes. Researchers are trying to improve the odds for patients with development of an implantable soft electronic monitoring system. Their new device, consisting of a smart stent and printed soft sensors, is capable of wireless real-time monitoring of hemodynamics without batteries or circuits.

Semiconductors are moving away from rigid substrates, which are cut or formed into thin discs or wafers, to more flexible plastic material and even paper thanks to new material and fabrication discoveries. The trend toward more flexible substrates has led to fabrication of numerous devices, from light-emitting diodes to solar cells and transistors.
