Investigating sources of inaccuracy in wearable optical heart rate sensors

Posted on February 22, 2020Categories TECHNOLOGY   Leave a comment on Investigating sources of inaccuracy in wearable optical heart rate sensors

As wearable technologies are being increasingly used for clinical research and healthcare, it is critical to understand their accuracy and determine how measurement errors may affect research conclusions and impact healthcare decision-making. Accuracy of wearable technologies has been a hotly debated topic in both the research and popular science literature. Currently, wearable technology companies are responsible for assessing and reporting the accuracy of their products, but little information about the evaluation method is made publicly available. Heart rate measurements from … Continue reading “Investigating sources of inaccuracy in wearable optical heart rate sensors”

In remote areas of the world or in regions with limited resources, everyday items like electrical outlets and batteries are luxuries. Health care workers in these areas often lack electricity to power diagnostic devices, and commercial batteries may be unavailable or too expensive. New power sources are needed that are low-cost and portable. Today, researchers report a new type of battery—made of paper and fueled by bacteria —- that could overcome these challenges. The researchers will present their results today … Continue reading “A paper battery powered by bacteria”

Humans have a hard time ‘killing’ robots, especially when they beg for their lives

In a recent paper in the journal PLOS ONE, German researchers asked 89 college students to team up with a tiny, bright-eyed robot named Nao to answer questions and complete menial tasks. It’s a robot partnership worthy of a buddy comedy. But, as is typical in experimental psychology, these tasks were a distraction from the real question under investigation: What happens when the humans had to turn the robot off? In 43 cases, the Verge reported earlier this month, “the robot protested, telling participants it was … Continue reading “Humans have a hard time ‘killing’ robots, especially when they beg for their lives”

Engineers Develop Multifunctional Flexible Robots Using MORPH System

Roboticists are envisioning a future in which soft, animal-inspired robots could be safely deployed in difficult-to-access environments, such as in delicate surgical procedures in the human body. Although centimeter-sized soft robots have been created, thus far it has not been possible to fabricate multifunctional, flexible robots that can move and operate at smaller size scales. A team of researchers at Harvard’s Wyss Institute for Biologically Inspired Engineering, Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), and Boston … Continue reading “Engineers Develop Multifunctional Flexible Robots Using MORPH System”

We need a drone register to ensure privacy and safety – air traffic expert

Requiring drones to identify and authorise themselves before they can fly, which could be achieved by fitting them with SIM cards, could help to protect people’s privacy by providing an effective way to register both users and machines, according to air traffic management expert Robin Garrity. He has been working on the U-space plan, which sets out a vision for how drones can be integrated into airspace, particularly in urban environments. It is part of work being conducted by the … Continue reading “We need a drone register to ensure privacy and safety – air traffic expert”

Robots working as a group are able to determine the optimal order of their tasks

Could robots soon help rescue crews save the survivors of a natural disaster? Such a mission would require that the robots be able to determine, on their own, which tasks to perform and in what order to perform them; for instance, there is no use attempting to pull a victim out of rubble if the rubble has not yet been cleared. Currently, engineers are responsible for programming the sequence of actions. But this could soon change! Mauro Birattari and Lorenzo … Continue reading “Robots working as a group are able to determine the optimal order of their tasks”

REDUCING THE NEED FOR 24-HOUR BLOOD PRESSURE MONITORS IN GENERAL PRACTICE

A new prediction tool for managing patients with suspected high blood pressure in primary care could reduce by half the number of people needing to wear 24-hour ambulatory blood pressure monitors to confirm a diagnosis of hypertension. High blood pressure – also known as hypertension – affects more than one in four adults in England. While often preventable, it is a leading cause of cardiovascular disease and is the biggest risk factor for death and disability internationally. A study led … Continue reading “REDUCING THE NEED FOR 24-HOUR BLOOD PRESSURE MONITORS IN GENERAL PRACTICE”

Engineer teaching humanoid robots to use their hands to stop themselves from falling

Posted on July 19, 2018Categories TECHNOLOGY   Leave a comment on Engineer teaching humanoid robots to use their hands to stop themselves from falling

A famous viral video about the DARPA Robotics Challenge shows all sorts of humanoid robots clumsily falling down. Bipedal movement is rather unstable, which is not only a problem for a robot trying to complete its task, but also because falling can damage a very expensive piece of machinery. Roboticists across the globe are tackling this problem in a myriad of ways. While some look to add a series of corrective steps after a robot becomes off-balance, much like a person stumbling … Continue reading “Engineer teaching humanoid robots to use their hands to stop themselves from falling”

Electronic stickers to streamline large-scale ‘internet of things’

Billions of objects ranging from smartphones and watches to buildings, machine parts and medical devices have become wireless sensors of their environments, expanding a network called the “internet of things.” As society moves toward connecting all objects to the internet—even furniture and office supplies—the technology that enables these objects to communicate and sense each other will need to scale up. Researchers at Purdue University and the University of Virginia have developed a new fabrication method that makes tiny, thin-film electronic … Continue reading “Electronic stickers to streamline large-scale ‘internet of things’”
