Recently, however, Wang and his team advanced the technology further by developing a skin-like wearable patch, which is both pliable and elastic and can monitor cardiovascular signals and multiple biochemical metrics like lactate, glucose, and alcohol in the body at the same time. “This is the first time that biometric and biological sensors are packed on the same patch.” But while the idea seemed sound in 2016, the engineering wasn’t there yet for scale-up. It demonstrated that packing several bulky sensors onto one miniaturized patch without having the signals interfere is possible.

That year, his laboratory introduced a proof-of-concept wearable array, dubbed Chem-Phys, to detect biometric information. Professor Wang’s research in wearables began in 2016. Observing how the dynamics of biochemical and biophysical data correlate to each other, we can not only understand how people react to what they eat and to environmental conditions but also become aware of subclinical manifestations which may lead to an eventual disease.” Because it can be worn on the wrist or the neck and can potentially communicate wirelessly with off-the-shelf digital devices, like smart watches and laptops Yin says, the device promises to have applications in other fields, like sport and entertainment, for monitoring athletic performance and fatigue.

“This patch will allow us to study your body’s response to these activities more closely and in real time. “We can establish correlations between your daily activities, seeing if your blood pressure goes up or down when you’re drinking alcohol, a cup of coffee, doing exercise or when you’re eating a meal,” says Lu Yin, the co-author of a new study describing the wearable device.
