New Smart Ring Uses Sweat to Track Glucose, Alcohol, and More

Leave a Comment / Engineering, Tech /

This new smart ring could provide insights that go well beyond sleep tracking and heart rate monitoring. Engineers at the University of California, San Diego have created an experimental smart ring that continuously examines sweat from the finger to track several molecules linked to metabolism, nutrition, physical activity, and alcohol intake. The prototype can simultaneously […]

Adaptive Prosthetic Hand Decodes 19 User Gestures in Real Time

Engineering, Tech /

Most prosthetic hands still face a fundamental challenge: every amputee has unique needs, yet most devices rely on a one-size-fits-all design. As a result, achieving natural, intuitive control remains difficult, often requiring users to spend significant time learning and adapting. Even with today’s sophisticated prosthetic technology, many users still struggle to control their devices. Muscle

A new smart bicycle can detect when a rider intends to turn and when they might be losing balance

Automotive, Electrical & Electronics /

Two-wheeled vehicles that use conventional stability-control systems need to lean to steer, which makes it challenging for rider-assistance technologies to tell whether a rider is deliberately turning or beginning to lose balance and risk a fall. To overcome this issue, researchers at Shibaura Institute of Technology (SIT) in Japan have created a rider-intent-aware control system

A new system improves electric vehicle battery safety and lifespan

Automotive, Engineering /

Like a conductor guiding an orchestra, a battery management system (BMS) regulates an electric vehicle’s power storage. Until now, it has relied only on measurements of individual cells—such as voltage, current, and temperature—while aging or damage could only be assessed indirectly through complex external calculations. In the EU-funded Nemo project, Graz University of Technology (TU

Volcanic rock–based formula reduces cement emissions by two-thirds

Electrical & Electronics, Engineering /

Researchers have created a volcanic rock–based formula that reduces carbon emissions by 67%, potentially providing a low-cost alternative to increasingly scarce cement additives. Cement—a manufactured powder that binds concrete—is the most widely used construction material in the world, but also one of the most polluting, responsible for nearly 8% of global greenhouse gas emissions. About

A new kitchen stove cooks food using water rather than natural gas

Engineering, Kitchen /

Greenvize has unveiled a compact hydrogen-powered cooking stove for both homes and commercial kitchens that can generate its own fuel from water. The device incorporates a proton exchange membrane (PEM) electrolyzer into a standard stove, enabling users to produce hydrogen whenever needed. It works by splitting water into hydrogen and oxygen through electrolysis. The hydrogen

Researchers are testing transparent wood as a glass alternative

Architecture, Engineering /

Transparent wood as a glass alternative could transform modern architecture by replacing brittle materials with a more sustainable option. This organic material provides much greater structural strength, contributing to safer building facades and improved urban thermal performance. In plants, stiffness and darkness come from lignin, a dense organic polymer that forms a cellular network responsible

Black Metal’ Solar Device Produces 15× More Power

Electrical & Electronics, Engineering /

Researchers have created a solar thermoelectric generator that delivers 15 times the efficiency of the latest leading devices. Researchers aiming for greater energy independence have investigated solar thermoelectric generators (STEGs) as a way to generate electricity from the sun. Unlike conventional photovoltaic panels, STEGs can harness both direct sunlight and other forms of thermal energy.

Engineers developed a light-activated gel that boosts ion conductivity 40o TIMES

Electrical & Electronics, Engineering /

Unlike rigid electronics, living systems are soft and flexible. MIT engineers developed a biocompatible, flexible gel whose light-controlled conductivity could advance human-machine interfaces and soft robotics. Welcome to the emerging field of ionotronics, which transmits information using ions—charged molecules—much like electronics relies on electrons. While electronic systems are established, ionotronics is still emerging—except in living
