Scientists develop “biological symbiosis device”: 3D printed custom wearable devices without charging

According to foreign media reports, wearable sensors for monitoring from steps to heart rate are almost everywhere.However, it is necessary to measure the onset of frailty in the elderly, diagnose fatal diseases in time, test the efficacy of new drugs, or track the performance of professional athletes.Medical treatmentClass equipment. Engineers at the University of Arizona have developed what they call “biology“Symbiosis Device” is a wearable device, which has several unprecedented benefits.

These devices are not only customized3D printingYes, and are based on the wearer’s body scan, and they can operate continuously using a combination of wireless power transmission and compact energy storage.Biology by the Faculty of Engineering

A team led by Philipp Gutruf, associate professor of engineering and Craig M. Berge Institute researcher, published its findings in the journal Science Advances on Friday.

Gutruf, a member of the university’s BIO5 Institute, said: “There is no such research yet. We have introduced a new concept, which is to directly tailor a device for a person and use wireless power for casting, allowing the device to run around the clock without charging. .”

Tailor-made suitability makes precise monitoring possible

Current wearable sensors face various limitations. For example, smart watches need to be charged, and because of their location on the wrist, they can only collect limited data.By using three-dimensional scans of the wearer’s body, including MRI, CT scans, and even meticulously combined smartphone images, Gutruf and his team can3D printingCustomized equipment, wrapped in various parts of the body. The ability to specialize sensor locations allows researchers to measure physiological parameters that they cannot measure.

“For example, if you want something that is constantly close to your core body temperature, you will want to put the sensor in your armpit. Or, if you want to measure the way your biceps deform during exercise, we can put a sensor in the device , This task can be accomplished,” said Tucker Stewart, a doctoral student majoring in biomedical engineering and the first author of the paper. “Because of the way we make the device and fix it to the body, we can use it to collect data that traditional, wrist-mounted wearable devices cannot collect.”

Since these “biosymbiosis devices” are customized for the wearer, they are also highly sensitive. Gutruf’s team tested the device’s ability to monitor parameters such as temperature and strain when a person jumps, walks on a treadmill, and uses a rowing machine. In the rowing machine test, the subjects wore multiple devices to carefully track the exercise intensity and the way the muscles deform. These devices are accurate enough to detect changes in body temperature caused by walking a flight of stairs.

Gutruf and his team are not the first to use wearable devices to track health and physical function. However, current wearable devices do not have the ability to continuously track indicators, nor do they have enough accuracy to draw medically meaningful conclusions.

Some wearable devices used by researchers are patches that are attached to the skin, but when the skin undergoes a normal shedding process, or sometimes when the subject sweats, they will fall off.even if
clinical
High-precision wearable devices such as electrocardiographs used on the Internet also face these problems. In addition, they are not wireless, which severely limits mobility. If patients are chained to bulky external equipment, they cannot carry out normal daily activities.
