Optical signal transmission can be significantly improved by limiting the wavelength of transmitted signals. Fiber Bragg grating (FBG) is a technique widely used in optical communication, sensing, and laser technologies for selectively blocking certain wavelengths […]
Growing up, we learn to push just hard enough to move a box and to avoid touching a hot pan with our bare hands. Now, a robot hand has been developed that also has these […]
Researchers at University of Tsukuba have developed a portable, silent subwoofer that combines electrical muscle stimulation with low-frequency vibrations. This device enables users to physically feel deep bass in virtual reality (VR) and everyday music. […]
Over the past few decades, electronics engineers have developed increasingly sophisticated sensors that can reliably measure a wide range of physiological signals, including heart rate, blood pressure, respiration rate and oxygen saturation. These sensors were […]
Researchers from the Istituto Italiano di Tecnologia (IIT) in Genoa (Italy) and Brown University in Providence (U.S.) have discovered that people sense the hand of a humanoid robot as part of their body schema, particularly […]
Researchers at National Taiwan University developed a new device that captures energy from vibrations more efficiently. Its self-adjusting mechanism enables resonance with environmental frequencies, resulting in higher power output across a broader operational range.This article […]
Apple’s unveiling of the latest batch of iPhones yesterday may have grabbed much of the attention, but the satellite messaging added to the Apple Watch Ultra 3 is an engineering marvel, says a Northeastern University […]
By challenging AI chatbots to judge thousands of moral dilemmas posted in a popular Reddit forum, UC Berkeley researchers revealed that each platform appears to follow its own set of ethics.This article was originally published […]
French lawmakers urged a social media ban for under-15s and “digital curfew” for older minors Thursday, with massively popular short video platform TikTok the focus of renewed harsh government scrutiny.This article was originally published on […]
China’s internet regulator said on Thursday it had ordered “warnings and strict punishment” to bosses at popular social media app Xiaohongshu over its online content, slamming “trivial” and “negative” posts.This article was originally published on […]
