Recent growth in space-related activities has presented numerous opportunities for electrochemistry in space. That’s why Greg Jackson, chair of the ECS High-Temperature Energy, Materials & Processes Division (H-TEMP) and mechanical engineering professor at the Colorado School of Mines, took it upon himself to bring the first-ever symposium dedicated to “Electrochemistry in Space” to the 236th ECS Meeting.
“As a board member and someone who cares about the Society expanding its audience, I felt that there are many activities going on in regards to applying electrochemistry in space and the uniqueness of the space environment merited a special symposium,” said Jackson, lead symposium organizer.
The potential for increased lunar and Martian activities with in situ resource utilization (ISRU), human space flight, and in-space satellite maintenance, and space debris management present many technical challenges and opportunities where electrochemistry plays a central role. (more…)
Editors’ Choice—Development of Screen-Printed Flexible Multi-Level Microfluidic Devices with Integrated Conductive Nanocomposite Polymer Electrodes on Textiles
Bonnie Gray, a professor at Simon Fraser University’s school of engineering science, was inspired by the city of Vancouver in British Columbia in her latest work.
“Vancouver is well-known for its technical clothing, and I have a lot of friends in the film industry who work in costume design. A combination of these influences and my own engineering background caused me to look further into integrating clothing with technology. That’s how I went on to become involved in developing screen-printed flexible multi-level microfluidic devices on textiles,” said Gray, which led to the fruition of her and lead author Daehan Chung‘s research paper, “Development of Screen-Printed Flexible Multi-Level Microfluidic Devices with Integrated Conductive Nanocomposite Polymer Electrodes on Textiles.”
In their open access paper, published in the Journal of The Electrochemical Society, the pair “present a flexible plastisol-based microfluidic process integrated with conductive nanoparticle composite polymer (C-NCP) electrodes for flexible active microfluidic devices on textile substrates.”
According to Gray, flexible and wearable microfluidic devices are among the newest wearable devices for applications in health monitoring, drug delivery systems, and bio-signal sensing. (more…)

“There are a lot of sensors that have been made, a lot of reliable sensors which work really well independently; however, the decision-making always requires a human,” said Ajit Khosla, sensors technical editor of the Journal of The Electrochemical Society (JES) and chair of The Electrochemical Society’s Sensor Division. Which is why the paper, “Artificial Intelligence Based Mobile Application for Water Quality Monitoring” piqued Khosla’s interest in particular.
“AI powered sensors are the future.”
“This is the first time that we have received and accepted a journal paper which involves artificial intelligence (AI), machine learning, water quality management, and sensors,” said Khosla. “This work represents an example of one of those initial steps towards a smart technology driven sustainable society where data acquired by sensors helps AI make human-like decisions or human-like operations. Quantum sensors, quantum computing, and AI will transform the way we live and will play an integral role in achieving sustainability and a sustainable world. AI powered sensors are the future.” (more…)
The recent fatal crash of a Boeing 737 Max 8 aircraft is forcing officials to take a closer look at the airplanes safety system. The accident—which happened just minutes after takeoff, killing all 157 passengers aboard the Ethiopian Airline—is suspected of being a result of a faulty sensory system built to stabilize the aircraft in flight, known as Maneuvering Characteristics Augmentation System (MCAS), according to USA Today.
Why was the MCAS added?
Boeing had originally added the MCAS after redesigning its 737 platform for the Max, changing the placement and size of the aircraft’s engines, consequently altering how the jet handled in flight. As a result, the Max tended to raise its nose in flight; a movement called pitch. If a plane pitches too high, it could lead to crashing or stalling of the aircraft—something the MCAS was installed to detect and prevent. (more…)
According to some scientists, humans are born with an innate sixth sense. And no, it’s not the ability to see ghosts like in the 1999 horror film. It’s the sense of proprioception: the perception or awareness of the position and movement of the body. This sense is what helps us coordinate our movements. For example, if you close your eyes, there remains a sense of awareness of where your muscles and body parts are located, the distance between them, and the perception of how they’re moving relative to one another, according to SingularityHub.
This complex sense is one that is difficult to recreate in robots, as solid state sensors traditionally used in robotics are unable to capture the high-dimensional deformations of soft systems. However, embedded soft resistive sensors have the potential to address this challenge. Using this approach, scientists are getting closer to overcoming the challenge with new techniques that involve an array of sensory material and machine-learning algorithms. (more…)
Tsunami warnings had initially broadcasted minutes before its arrival; unfortunately, underestimating its size. Many failed to evacuate to higher ground as a result; a total of 15,894 deaths resulted from the natural disaster. Japan has since installed a network of seismic and pressure sensors on the ocean floor that have raised the bar for tsunami early-warning systems worldwide.
New research, which appears in Geophysical Research Letters, suggests how warnings could be more accurate by combining data streaming in real-time from sensors, like those in Japan, with tsunami simulations.
Researchers have recently discovered that light sensors might be able to help with that. According to New Food, the sensors work by actively measuring the various wavelengths of light coming off of crop leaves. These measurements are then used to calculate how much nitrogen crops need for optimal health. (more…)
