Colonoscopy-like Bacteria Grabber

Purdue University researchers have built a way to swallow a tool that acts like a colonoscopy, except that instead of looking at the colon with a camera, the technology takes samples of bacteria. The tool is a drug-like capsule that passively weasels through the gut without needing a battery. The technology could also move throughout the whole GI tract, not just the colon. This tract, in addition to the colon, includes the mouth, esophagus, stomach, pancreas, liver, gallbladder, small intestine and rectum. Essentially, this tool would make it possible to conduct a “gut-oscopy.” An initial demonstration of the prototype is published in RSC Advances, a journal by the Royal Society of Chemistry.

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.”

Self-moisturising Smart Contact Lenses

Researchers at Tohoku University have developed a novel kind of smart contact lenses which are self-moisturising preventing eyes from dryness. The self moisturising system maintains a layer of fluid between the contact lens and the eye.

        The common problem with contact lenses is that they often cause "dry eye syndrome" due to less blinking and increased moisture evaporation. In order to tackle this problem, the researchers have developed a novel mechanism to keep the lens moist. The system uses Electro-osmotic Flow (EOF), which allows liquid to flow when a voltage is applied across a charged surface. The research is published in the journal Advanced Materials Technologies.

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.
