ELEGOO sent us the Saturn 4 Ultra 16K Resin 3D printer for review. As its name implies, the 3D printer features a 10-inch LCD ...

Lasers enable the U.S. Navy to fight at the speed of light. Armed with artificial intelligence (AI), ship defensive laser ...

Wearable sweat biosensors enable the non-invasive, real-time monitoring of hormones. Here, we highlight the development and commercialization of a wearable technology that can measure hormone ...

Biosensors are devices used to detect the presence or concentration of a biological analyte, such as a biomolecule, a biological structure or a microorganism. Biosensors consist of three parts: a ...

The best color laser printers are a great investment that can save you time and money compared to cartridge-based inkjet printers. Laser printers use toner, which lasts a long time, delivering a ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2025.240275, discusses A highly sensitive laser gas sensor based on a four-prong ...

As newbies to at-home IPL and laser hair removal, we really enjoyed the skin tone sensor feature, as it helped recommend the best intensity (out of the five available) based on skin tone.

The weapon not only can use a high-energy laser to destroy targets, but is designed to disrupt intelligence-gathering efforts and reconnaissance sensors from adversaries. The Navy plans to ...

The USS Preble is the only U.S. destroyer armed with the HELIOS, which can fire laser beams to destroy fast attack craft and drones.

In this paper, a dual-pulse heterodyne distributed acoustic sensor (DAS) system using a semiconductor optical amplifier (SOA)-based fiber ring laser (FRL) is proposed. Unlike the previous DAS system ...

The HP LaserJet M209d is a sterling value among low-cost, print-only mono laser printers. (If you're considering an inkjet but print only occasionally, it's a tempting alternative.) Its paper ...

If implemented, this technology could buttress the operation of sensors and navigation systems ... “pull” free-falling atoms that have been laser-cooled and super-positioned into multiple ...
