Sensor for Alcohol Detection through Breath Monitoring

Indian Institute of Technology Jodhpur researchers have developed the first “Make in India” human breath sensor based on metal oxides and nano silicon operating at room temperature. The device’s primary function is to measure alcohol content in the breath in drunk and driving cases. Moreover, the developed sensor also does not require any extra batteries or preparation time.

                However, with some changes in sensing layers and the use of an array of sensors (for Electronic Nose or Artificial Nose), and data analytics, it can also be very useful for characterisation of diseases, such as asthma, diabetic ketoacidosis, chronic obstructive pulmonary disease, sleep apnea, and cardiac arrest, where the person's breath volatile organic compounds are monitored. The study was published in the journal IEEE Sensors Letters.

Infection-resistant, 3D-printed metals for implants

Researchers from Washington State University developed a novel surgical implant, able to kill 87% of the bacteria that cause staph infections in laboratory tests while remaining strong and compatible with surrounding tissue like current implants. The work, reported in the International Journal of Extreme Manufacturing.

                According to researchers, the development could someday lead to better infection control in many common surgeries, such as hip and knee replacements, that are performed daily around the world. Bacterial colonisation of the implants is one of the leading causes of their failure and bad outcomes after surgery. Additionally, the biggest advantage of this type of multifunctional device is that one can use it for infection control as well as for good bone tissue integration, according to researchers.

BRAHMA-2D Model Revolutionises Hydraulic Design for Sustainable River Management

Researchers at the  IIT Guwahati in collaboration with the Brahmaputra Board, Ministry of Jal Shakti, Government of India, have developed an indigenous river model BRAHMA-2D (Braided River Aid: Hydro-Morphological Analyzer). This comprehensive mathematical model can help to understand the flow of large braided rivers, providing valuable insights to field engineers to design sustainable hydraulic structures like Spurs, Revetment and other river bank protection measures.

                Predicting river flow variations across depth is crucial for flood and erosion control, agriculture and water supply intake design, and zero head energy production. Traditional measurement methods of flow velocity in deep, large rivers during high monsoons are risky and extremely difficult, prompting the use of mathematical models. However, existing models provide only average velocity, underestimating undercurrents at different depths. In braided rivers, the presence of sandbars further complicates accurate three-dimensional velocity computation. The findings were published in the journal ISH Journal of Hydraulic Engineering.

Bio-logger — Records the Rare Behaviours of Wild Animals

It’s always exciting to notice the unusual activities of animals, which are simultaneously difficult to catch. Their rare behaviours are not captivating to humans only; they are of great interest to scientists to get new insights into the research. Since their infrequent behaviours are not readily observable for various reasons, the details of their behaviours remain elusive. However, to overcome this constraint, researchers from Osaka University in Japan have developed a tiny artificial intelligence-based ‘Bio-logger’, a small sensor-based data logger. The Bio-logger automatically captures the video of the target animal’s rare behaviour without the researcher’s supervision. The study published in PNAS Nexus offers an approach to documenting the rare behaviours of animals that were overlooked earlier and facilitating our understanding of target animal behaviours.

Sensor for Rapid Water Quality Monitoring

Researchers from IIT Delhi’s Department of Biochemical Engineering and Biotechnology have developed a sensor for real-time water quality monitoring using electricity-generating microorganisms. Known as “electroactive microorganisms”, these microbes generate an electrical current and are widely researched for power generation but can also be used for biosensing.

                The sensor uses “weak electricigen”, a category of electroactive microbes, known for generating low levels of electricity. When the weak electricigens encounter a pollutant, their current output decreases. By measuring their extracellular current continuously, the approach facilitates real-time monitoring of water quality.

Virtual Reality Goggles for Mice

Researchers from Northwestern University have developed new Virtual Reality (VR) goggles for mice called Miniature Rodent Stereo Illumination VR (iMRSIV). According to researchers, these miniature goggles provide more immersive experiences for mice living in laboratory settings. By more faithfully simulating natural environments, the researchers can more accurately and precisely study the neural circuitry that underlines behaviour.

                Additionally, researchers used the goggles to simulate an overhead threat — something that had been previously impossible with current systems. The system comprises two lenses and two screens — one for each side of the head to separately illuminate each eye for 3D vision, which provides each eye with a 180-degree field-of-view that fully immerses the mouse and excludes the surrounding environment. The research was published in the journal Neuron.

Cobalt-free Battery for Cleaner, Greener Power

A wide variety of elements are used in the production of high-capacity and reliable rechargeable batteries, including cobalt, the production of which contributes to some environmental, economic and social issues. To tackle the issue, a team including researchers from the University of Tokyo introduced new electrodes and electrolytes.

                The new electrodes and electrolytes are not only devoid of cobalt, but they actually improve upon current battery chemistry in some ways. The new LIBs’ energy density is about 60% higher, which could equate to longer life, and it can deliver 4.4 volts, as opposed to about 3.2-3.7 volts of typical LIBs. Additionally, the test batteries with the new chemistry were able to fully charge and discharge over 1,000 cycles (simulating three years of full use and charging), whilst only losing about 20% of their storage capacity.

Micro Heat Engine High power achieved with high efficiency

Designing a heat engine that can produce maximum power at maximum efficiency is a major challenge. Practical heat engines are limited to a theoretical efficiency called the Carnot limit, which sets a cap on how much heat can be converted to useful work. In a breakthrough, researchers at the Indian Institute of Science (IISc) and Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) have devised a novel “micro heat engine” that has overcome this limitation at the lab scale. The study was published in Nature Communications.

                According to researchers the unique micro-scale engine operates with just one particle. Additionally, the size of the engine is very small, about 1/100th the width of a single human hair.

Researchers achieve near-perfect light absorption in atomic-scale material

A University of Minnesota-led team has engineered an atomically thin material that can absorb nearly 100% of light at room temperature, a discovery that could improve a wide range of applications from optical communications to stealth technology. The paper is published in Nature Communications, 
                    Materials that absorb nearly all of the incident light — meaning not a lot of light passes through or reflects off of them — are valuable for applications that involve detecting or controlling light.
                  The researchers made this “near-perfect absorber” possible by using a technique called band nesting to manipulate the already unique electrical properties in a material made up of only two to three layers of atoms. Their fabrication method is simple, low-cost and requires no nano-patterning methods, which means it’s easier to scale up than that of other light-absorbing materials being studied.

Shape-changing smart speaker lets users mute different areas of a room

A team led by researchers at the University of Washington has developed a shape-changing smart speaker, which uses self-deploying microphones to divide rooms into speech zones and track the positions of individual speakers. The findings are published in Nature Communications. 
                   With the help of the team’s deep-learning algorithms, the system lets users mute certain areas or separate simultaneous conversations, even if two adjacent people have similar voices. Like a fleet of Roombas, each about an inch in diameter, the microphones automatically deploy from, and then return to, a charging station. This allows the system to be moved between environments and set up automatically. In a conference room meeting, for instance, such a system might be deployed instead of a central microphone, allowing better control of in-room audio.

Highly Efficient Spintronics-based Neuromorphic Hardware

Interactive voice assistants have made it very easy to obtain a response to a query or get tasks done online. However, it involves delivering the speech data to the cloud over the internet, processing the data in the cloud, and then providing a response to the device. But due to slow internet speed, power outages, and other factors, speech data is frequently lost.

Affordable and Effective Face Mask — KAWACH

The IIT Delhi start-up, ETEX has launched an affordable and effective face mask namely KAWACH to protect and safeguard people from the risk of COVID-19. Prof. Bipin Kumar, Textile and Fiber Engineering Dept., IIT Delhi said, “India has several massive challenges ahead – disposal of PPEs (including mask and coveralls) after one-time use and ensuring the minimum use of nonwoven technology for making PPEs. Though a nonwoven layer is must for ensuring the desired filtration level but the loose fibrous structure makes the product disposable after one use. Disposing of synthetic polypropylene nonwoven could have a detrimental effect on the environment. Finding other textile solutions that offer reusability, biodegradability, affordability and scalability for PPEs is the need of the hour; this could ensure meeting both the demand and also safeguarding our environment.”

Electronic Skin — Human-machine Interface

Wei Gao, assistant professor at Caltech’s Andrew and Peggy Cherng Department of Medical Engineering, has developed an electronic skin, or e-skin, which can be applied directly on top of the real skin. The newly developed e-skin which is made from soft, flexible rubber, can be embedded with sensors. These sensors can monitor information like body temperature, heart rate, levels of blood sugar and metabolic byproducts that are indicators of health, and even the nerve signals that control our muscles. It does not require a battery, as it runs solely on biofuel cells powered by one of the body's own waste products.

        According to Gao, “One of the major challenges with these kinds of wearable devices is on the power side. Many people are using batteries, but that's not very sustainable. Some people have tried using solar cells or harvesting the power of human motion, but we wanted to know, 'Can we get sufficient energy from sweat to power the wearables?' and the answer is yes.”

Edible “Security Tags” Protecting Drugs from Duplicacy

Purdue University researchers have designed an edible “security tag” to tackle the problem of counterfeiting of drugs. The security tag can be embedded in medicine. To copy the drug, a counterfeiter would have to solve a complicated puzzle of patterns not completely visible to the naked eye.

        The tag serves as a digital fingerprint for a drug capsule or tablet. It uses a verification technique called “physical unclonable functions,” or PUF. PUFs generate a different response once stimulated, rendering them unpredictable and very difficult to imitate. It is the first edible PUF – a thin, transparent film made up of silk proteins and fluorescent proteins which are fused genetically. As the tag is easily digestible and made entirely of proteins, it can be consumed as part of a pill or tablet. The research has been published in the journal Nature Communications.
