China Security Exhibition Network Technology News Not long ago, American engineering personnel developed the world's first all-electronic integrated system that can continuously monitor multiple chemical compounds in sweat without harm. Not long ago, American engineering personnel developed the world's first all-electronic integrated system that can continuously and harmlessly monitor a variety of biochemicals in sweat. This new technology opens the door to wearable devices. When users experience health problems such as excessive fatigue, dehydration, and excessive body temperature, it will immediately issue an alert. What can a new wearable sensor reveal from sweat? Engineers at the University of California gave the results.
The latest wearable sensor can monitor your sweat biochemicals
Accurately speaking, this "sensitive sensor system" can measure sweat metabolites and electrolytes according to the temperature of the user's skin and synchronize the data to the smart phone in real time. Although in the past decade, many health monitoring systems have appeared on consumer electronics devices, the researchers said that the new device debuted in Nature magazine is the world’s first all-electronic integrated system. .
Ali Jevy, a professor from the Department of Electrical Engineering and Computer Science at the University of California, is the lead researcher of the project. He said: "Human sweat contains a wealth of physiological information, which provides a unique 'no harm to wear sensors' Attractive test articles.However, the sweating process is complicated and needs to extract effective skin-related information from many aspects.So we developed an all-electronic integrated system that can selectively Measure multiple sweat analytes and wirelessly transmit analysis data to smartphones. Our work opens a new technology platform for sweat-based health monitoring.â€
In order to design and develop this “sweat sensing systemâ€, Jie Wei and his team specifically consulted with exercise physiologist and George Brokes, professor of integrated biology at the University of California. Bullocks said that he was deeply attracted by the sensors designed by the Czech-Weifang research team.
As a collaborator of this research, he felt that it was incredible to make a wearable sweat sensor, because the metabolites and electrolytes measured in this new device are very important for personal health. “Without harmless technology, one day we will no longer need to take a single shot and we will know how we are physically,†he said.
From the sample made by the research team, it can be seen that there are five sensors in a flexible circuit board. These sensors measure glucose and lactate of metabolites, sodium and potassium in electrolytes, and skin temperature. The integrated system allows researchers to calibrate and match the readings of other sensors in real-time by measuring skin temperature, because the glucose and lactate sensor's response is very temperature-dependent.
Adjacent to the sensor is a wireless transmission circuit board made of ready-made silicone originals. The researchers used more than 10 integrated circuit chips to take charge of sensor measurements, signal enhancements, adaptations to body temperature changes, and wireless data transfer. In addition, they also created a special app (mobile phone software) to synchronize the sensor's data to the phone and connect it to the smart bracelet and headband.
In the experiment, the researchers distributed the equipment to volunteers performing a variety of indoor and outdoor sports. The goal was to pedal bicycles or run outdoors. The test time ranged from several minutes to as much as one hour. Through a series of tests, they hope to integrate all circuit functions into a single chip in the future. This will reduce the size of the device and measure more results at a time.
Brooks believes that this "sensor" is full of potential, and it may be used in the future to measure other than sweat. He said: "Since this kind of 'wearable technology' can be applied to athletes, there may be more scientific applications, such as measuring the metabolites and electrolyte levels that are crucial to people's daily health. Or measure other body fluids for injured or sick people."
Chief researcher Jie Wei said that their long-term goal is to apply this device to medical application research.
