This premium article gives an overview of optical combiners and explores manufacturing methods for surface relief diffractive waveguides, with examples from key market players.

Researchers created a special ultrathin sensor, spun from gold, that can be attached directly to the skin without irritation or discomfort. The sensor can measure different biomarkers or substances to perform on-body chemical analysis. It works using a technique called Raman spectroscopy, where laser light aimed at the sensor is changed slightly depending on whatever chemicals are present on the skin at that point. The sensor can be finely tuned…

Virtual Reality (VR) headsets are edging toward becoming commonplace. However, social acceptability is still some way off and the user experience is not entirely comfortable. Essential to solving these problems are the lenses that magnify and focus headsets' displays.

This premium article explores the TechConnect 2022 event, held from 13th-15th June near Washington DC. The event covered a wide range of technologies and this article will particularly focus on photonics, displays, and augmented reality, materials informatics and AI, and materials and electronics.

Wearable activity trackers that monitor changes in skin temperature and heart and breathing rates, combined with artificial intelligence, might be used to pick up COVID-19 infection days before symptoms start, suggests preliminary research.

Blood pressure is one of the most important indicators of heart health, but it's tough to frequently and reliably measure outside of a clinical setting. For decades, cuff-based devices that constrict around the arm to give a reading have been the gold standard. But now, researchers have developed an electronic tattoo that can be worn comfortably on the wrist for hours and deliver continuous blood pressure measurements at an accuracy level…

This premium article explores the PRINSE'22 event. It will look into the most interesting and commercially relevant presentations from the event, with a focus on integrated electronics, manufacturing, wearable technology, and biological sensing.

A Finnish research group has developed a novel wearable for infants for the reliable assessment of motor abilities during early development. The smart jumpsuit is a wearable medical device equipped with multiple movement sensors, which assist in assessing and predicting children's neurological development.

The creation of high-resolution extrusion printing—think 3D printing but with ink that conducts electricity—has enabled researchers to explore the potential of wearable human motion devices.

A coach wearing a mixed-reality headset could receive real-time statistics and facial interpretation data to evaluate a player, while also interfacing with a team of analysts and trainers who work remotely and see the same information.
