D
Scientists from the Hefei Institutes of Physical Science (HIPS) have designed a wristwatch that can measure essential chemicals in body sweat. Their findings were published in the journal ACS Nano.
Sweat contains electrolytes (电解质), mainly potassium, sodium and calcium. The balance of these minerals is crucial for (对……至关重要) supporting muscle function, nerve health and regular heartbeat. The wristwatch collects sweat from the skin and analyzes it in real time using a sensor chip with a sensitive membrane (膜). When sweat enters the device, it will come into contact with (与……产生接触) the membrane that is capable of measuring sodium, potassium and calcium levels.
Although they are not the first to invent sweat sensors, these Chinese researchers highlighted the wristwatch’s solid interface for long-term reliability. “It surpasses the stability of many other sensors by continuously monitoring human sweat for over six months,” said the lead researcher Huang Xingjiu.
Researchers in the study measured the sweat composition of the essential chemicals in athletes running long distances, as they are seen as providing a typical example of electrolyte variations over a long time span. The measurement’s accuracy reached about 95 per cent, far higher than that of the standard detection method previously used.
For ordinary people, the traditional electrolyte test requires samples of body fluids taken in hospitals. The new wristwatch has the potential to serve as a portable new option that can be carried around in our everyday lives and does not require a trip to the doctor’s office.
The next goal of the research team is to design various sensitive membrane materials for monitoring more kinds of information. The researchers noted that compared to popular fitness watches on the market, the device they designed is larger and heavier, making it less comfortable to wear. However, they expect to develop wearable sweat sensors suitable for market applications (市场应用) in the next five years. The team of researchers also aims to adapt the device for environmental monitoring.
