Researchers have developed a smart necklace called ‘SmokeMon’ that helps keep a track of your smoking habits with every puff you smoke. The researchers at the Northwestern Medicine have developed a neck-wearable device that resembles a lapis blue pendant necklace that tracks heat when you smoke a cigarette. The necklace can also track how much a smoker inhales, and the time between puffs.
“We can detect when the cigarette is being lit, when the person holds it to their mouth and takes a puff, how much they inhale, how much time between puffs and how long they have the cigarette in their mouth, said senior investigator Nabil Alshurafa, associate professor at the Northwestern University Feinberg School of Medicine.
“For many people who attempt to quit smoking, a slip is one or two cigarettes or even a single puff. But a slip is not the same as a relapse (going back to smoking regularly). A person can learn from slips, by gaining awareness that they did not fail, they just had a temporary setback,” Alshurafa added.

With the SmokeMon smart necklace, users can gain a better understanding of the relationship between tobacco-related diseases such as cancer, heart disease, stroke, lung disease, diabetes, COPD, emphysema and chronic bronchitis by assessing chemical exposure.

The smart necklace has been developed to measure what’s called smoking topography which is essentially an assessment of how much carbon monoxide is a smoker exposed to and provides actionable insights to help those tryin to quit smoking.

Smart Necklace Biosensor Monitors Glucose Levels Through Sweat

A device that might one day utilize the chemical indicators in sweat to identify changes in a person’s health has successfully undergone testing by researchers.

A team from The Ohio State University recently presented a wireless, battery-free biochemical sensor that could detect the blood sugar, or glucose, that individuals release from their skin when they exercise. The work was published in the journal Science Advances.

The Ohio State researchers created a “smart necklace” that included a working clasp and pendant and was worn around the participants’ necks to track their blood glucose levels as they exercised.

It operates without a battery by reflecting radio frequency signals from an external reader system using a resonance circuit. Participants cycled for a minimum of 30 minutes, had a 15-minute rest, and then resumed cycling after consuming sugar-sweetened drinks.

According to Jinghua Li, co-author of the work and assistant professor of materials science and engineering at Ohio State, the challenge was whether this novel sensor would detect the rise in sweat glucose levels that should occur after consuming a sweetened beverage.

The sensor did effectively track the glucose levels, according to the data, which implies that it will also be able to detect other significant compounds in sweat.

Sweat actually contains hundreds of biomarkers that can reveal very important information about our health status. The next generation of biosensors will be so highly bio-intuitive and non-invasive that we will be able to detect key information contained in a person’s body fluids.

Smart Necklace Can Track Blood Sugar Through Sweat

Jewelry of the future may be used not only as a fashion accessory, but also to monitor aspects of a person’s health, thanks to new research from The Ohio State University. Researchers there have developed a device that can be worn around the neck to monitor a person’s glucose levels from sweat excreted when he or she exercises, they said. It could one day be used as a way to help people with diabetes to keep track of their blood sugar without painful pin pricks, they said. The so-called “smart necklace” includes a typical clasp and pendant, but also features a battery-free, wireless biochemical sensor that researchers used to measure test subjects’ blood sugar through their perspiration, they said.

“Sweat actually contains hundreds of biomarkers that can reveal very important information about our health status,” Jinghua Li, assistant professor of materials science and engineering at Ohio State, stated in an article in Ohio State News. “The next generation of biosensors will be so highly bio-intuitive and non-invasive that we’ll be able to detect key information contained in a person’s body fluids.”

Indeed, scientists are finding human perspiration a useful natural component for novel wearable-device design. A research team from Penn State University already has used sweat to measure glucose with the development of a non-invasive patch-like sensor made with a nickel-gold alloy.

Meanwhile, engineers at the University of California (UC) San Diego developed a wearable microgrid that harvests energy from various renewable sources—including perspiration—to power small electronic devices.

Smart Necklace Design

While the smart necklace designed by the Ohio State team doesn’t use sweat to power the device, it does work without a battery by using a resonance circuit, which reflects radio frequency signals sent out by an external reader system for power, researchers said. The sensor is made
