Smart necklace with glucose measurement function

2022: Device Announcement

In early August 2022, Ohio State University researchers unveiled a device that can be worn around the neck to monitor a person's glucose levels by sweat secretions during exercise.

The device could be used to help people with diabetes monitor their blood sugar levels without painful jabs, the developers said. The smart necklace includes a regular clasp and suspension, but also features a cordless biochemical sensor without batteries, which the researchers used to measure the blood sugar levels of the subjects through their sweat.

In August 2022, engineers from the University of California, San Diego, developed a wearable microgrid that collects energy from various renewable sources, including sweat, to power small electronic devices. The smart necklace does not use sweat to power the device, it works without a battery due to the use of a resonant circuit that reflects radio frequency signals sent by an external reading system to obtain energy. The sensor is made of lightweight, ultra-thin materials that give it flexibility, and also includes a protective layer that protects both the device and human skin.

The researchers tested the necklace on study participants who did indoor cycling for 30 minutes and then took a 15-minute break during which they drank sugar-sweetened drinks before returning to the exercise bike.

{{quote 'Sweat contains hundreds of biomarkers that can reveal very important information about the state of our health. The next generation of biosensors will be so biointuitive and noninvasive that we can detect key information contained in human body fluids. We hope that ultimately these sensors can be easily integrated into our personal belongings, "said Ohio State University Assistant Professor of Materials Science and Engineering Jinghua Li. }} The results of the sensor showed that it is able to capture the increase in glucose levels caused by drinking sugary drinks, which scientists believe is promising in terms of its ability to capture other chemical biomarkers in sweat, the researchers said. In addition, a lot of sweat was not required to measure the participants' blood sugar levels. Scientists reported the results of their study in an article published in the journal Science Advances.^[1]
