Researchers at Australia’s Monash University developed an ultra-thin skin patch equipped with a sensor made from laminated cracked platinum film, vertically aligned gold nanowires and a percolated gold nanowire film that is able to monitor 11 human health signals.

In a paper published in the journal Nature Nanotechnology, the scientists explain that their goal was to combine nanotechnology and artificial intelligence to bring machines one step closer to communicating with the human body.

According to the group, personalized AI technology using specialized algorithms can now disentangle multiple body signals, understand them and decide what to do next.

Worn on the neck, the ultra-thin wearable patch has three layers, measuring speech, neck movement and touch. It also measures breathing and heart rates.

“Emerging soft electronics have the potential to serve as second-skin-like wearable patches for monitoring human health vitals, designing perception robotics and bridging interactions between natural and artificial intelligence,” lead researcher Wenlong Cheng said.

The new development is based on a frequency/amplitude-based neural network called Deep Hybrid-Spectro, that can automatically monitor multiple biometrics from a single signal.

“As people all sound and act differently, the next step is to program and personalize the sensors using even more sophisticated algorithms so they can be tailored to individuals,” Zongyuan Ge, co-author of the study, said.

Ge explained that the sensor goes on the neck because its skin is the most sensitive skin on the body and connects up to five physiological activities associated with the human throat: speech, heartbeats, breathing, touch and neck movement.
