Multi-Tasking Wearable Continuously Monitors Glucose, Alcohol, and Lactate
Imagine being able to measure your blood sugar levels, know if you've had too much to drink, and track your muscle fatigue during a workout, all in one small device worn on your skin. Engineers at the University of California San Diego have developed a prototype of such a wearable that can continuously monitor several health stats—glucose, alcohol, and lactate levels—simultaneously in real-time.

Silicon-carbide modulator overcomes decades long ’missing block’
A collaboration with Harvard University has led to the development of a new-generation electro-optic modulator that could stamp out its bulky predecessor through the creation of a smaller, stronger, cooler, faster and cost-effective on-chip system. The new modulator was made possible through the harnessing of a 'difficult' compound - silicon carbide.

Engineered crystals could help computers run on less power
Researchers at the University of California, Berkeley, have created engineered crystal structures that display an unusual physical phenomenon known as negative capacitance. Incorporating this material into advanced silicon transistors could make computers more energy efficient. (UC Berkeley image by Ella Maru Studio) Computers may be growing smaller and more powerful, but they require a great deal of energy to operate.

Speed Limit of Computers detected
By Christoph Pelzl One million gigahertz: This is the physical limit of the signal speed in transistors, as a German-Austrian physics team has now discovered. The maximum speed of signal transmission in microchips is about one petahertz (one million gigahertz), which is about 100,000 times faster than current transistors.

Scientists create new lead-free piezoelectric materials
Researchers have discovered that gadolinium-doped cerium oxide, a compound they created in the lab, could be a promising alternative to certain piezoelectric materials: it has the same proprieties yet may be 100 times more effective. It's also lead-free, unlike the best piezoelectric materials, which means that it could be employed in bio-compatible medical applications.

Waves on circular paths
Just as electrons flow through an electrical conductor, magnetic excitations can travel through certain materials. Such excitations, known in physics as "magnons" in analogy to the electron, could transport information much more easily than electrical conductors. An international research team has now made an important discovery on the road to such components, which could be highly energy-efficient and considerably smaller.

TU Ilmenau develops resource-efficient energy distribution network for Germany
In the spirit of the energy transition, TU Ilmenau is developing a resource-efficient power distribution grid for Germany. Such a power grid, based on direct current technology, will be specifically tailored to the increasing use of renewable energy generated in a large number of decentralized plants and will offer significantly higher operational reliability than the current grid.

Quantum tech: Semiconductor ’flipped’ to insulator above room temp
A semiconducting material that performed a quantum "flip” from a conductor to an insulator above room temperature has been developed at the University of Michigan. It potentially brings the world closer to a new generation of quantum devices and ultra-efficient electronics. Observed in two-dimensional layers of tantalum sulfide only a single atom thick, the exotic electronic structure that supported this quantum flip was previously only stable at ultra-cold temperatures of -100 degrees Fahrenheit.
