Transient pacemaker harmlessly dissolves in body

The thin, flexible, lightweight device could be used in patients who need temporary pacing after cardiac surgery or while waiting for a permanent pacemaker. All components of the pacemaker are biocompatible and naturally absorb into the body's biofluids over the course of five to seven weeks, without needing surgical extraction.

Using the ancient art of Kirigami to make an eyeball-like camera

Using Kirigami, the Japanese art of paper cutting, a mechanical engineer has developed a camera with a curvy, adaptable imaging sensor that could improve image quality in endoscopes, night-vision goggles, artificial compound eyes and fish-eye cameras.

Transforming the layered ferromagnet F5GT for future spintronics

Engineers have achieved record-high electron doping in a layered ferromagnet, causing magnetic phase transition -- with significant promise for future electronics. Control of magnetism by electric voltage is vital for developing future, low-energy high-speed nano-electronic and spintronic devices, such as spin-orbit torque devices and spin field-effect transistors.

Backscatter breakthrough runs near-zero-power IoT communicators at 5G speeds everywhere

Researchers have found a low-cost way for backscatter radios to support high-throughput communication and 5G-speed Gb/sec data transfer using only a single transistor when previously it required expensive and multiple stacked transistors.

Unbroken: New soft electronics don't break, even when punctured

A team of researchers has created a new type of soft electronics, paving the way for devices that are self-healing, reconfigurable, and recyclable. These skin-like circuits are soft and stretchy, sustain numerous damage events under load without losing electrical conductivity, and can be recycled to generate new circuits at the end of a product's life.

Recycling next-generation solar panels fosters green planet

Designing a recycling strategy for a new, forthcoming generation of photovoltaic solar cells - made from metal halide perovskites, a family of crystalline materials with structures like the natural mineral calcium titanate - will add a stronger dose of environmental friendliness to a green industry, according to new research.

Inkjet printing 'impossible materials'

Engineers developed inexpensive methods to make 'impossible materials' that interact in unusual ways with microwave energy. Thin film polymers inkjet printed with tiny component patterns collect or transmit energy with much greater selectivity, sensitivity, and power than conventional materials.
