Chinese researchers design wristwatch for real-time health monitoring through sweat
一滴汗”就能監測健康狀況？
Scientists from the Hefei Institutes of Physical Science (HIPS) under the Chinese Academy of Sciences have designed a wristwatch that can measure essential chemicals in body sweat. Their findings were published in the journal ACS Nano.
中國科學院合肥物質科學研究院的科學家們研發了一款可以測量汗液中必需化學物質的腕表。他們的研究結果發表在《ACS Nano》期刊上。
Sweat contains electrolytes, primarily potassium, sodium and calcium. The balance of these essential minerals is crucial for supporting muscle function, nerve health and regular heartbeat.
汗液中含有電解質，主要是鉀、鈉和鈣。研究人員表示，這些必需礦物質的平衡對維持肌肉功能、神經健康和規律心跳至關重要。
The wristwatch collects sweat from the skin and analyzes it in real time using a sensor chip with an ion-sensitive membrane. When sweat enters the device, it will come into contact with the membrane that contains three tubules capable of measuring sodium, potassium and calcium levels, respectively.
這款腕表可以從皮膚上收集汗液，并使用帶有離子敏感膜的傳感器芯片實時分析汗液。當汗水進入設備時，它會接觸到含有三個小管的離子敏感膜，這些小管分別可以測量鈉、鉀和鈣的含量。
Although they are not the first to invent sweat sensors, the Chinese researchers emphasized the wristwatch's solid interface for long-term reliability.
雖然這不是汗液傳感器第一次問世，但研究人員強調，該腕表的固體接觸層可以保證它長期耐用。
"It surpasses the stability of many other sensors by consistently monitoring the three ions in human sweat for over six months," said lead researcher Huang Xingjiu, of the Institute of Solid State Physics under the HIPS.
該研究的首席研究員，來自中國科學院合肥物質科學研究院的黃行九說:“（我們使用該傳感器）持續監測了人體汗液中的三種離子六個多月，發現該傳感器的穩定性超過了許多其他傳感器。”
Since endurance athletes use electrolyte drinks to counteract the loss of energy and replenish it, researchers in the study measured the sweat composition of these chemicals in athletes running long distances on a treadmill. The accuracy reached approximately 95 percent when compared to the standard detection method.
由于耐力運動員會飲用電解質飲料來補充能量和電解質，研究人員在這項研究中測量了運動員在跑步機上長跑產生的汗液中化學物質的組成。與標準檢測方法測量的結果相比，該傳感器測量的結果準確度達到95%左右。
"When there are electrolyte abnormalities, the device will remind users to supplement them promptly. The aim of developing this device is to provide warnings for electrolyte loss and reduce exercise-related injury risks."
研究人員解釋道：“當電解質異常時，該設備會提醒用戶及時補充電解質。開發這種設備的目的是為電解質流失提供警告，降低與運動相關的傷害風險。”
For ordinary people, the conventional electrolyte test requires samples of body fluids taken in hospitals. The new wristwatch has the potential to serve as an alternative to needles for measuring electrolytes.
對于普通人來說，傳統的電解質測試需要在醫院采集體液樣本。這款腕表有可能替代針管，成為測量電解質的新工具。
The next goal of the research team is to design various sensitive membrane materials for monitoring more physiological information, such as glucose and chloride ions.
研究小組的下一個目標是設計不同的敏感膜材料，以監測更多生理信息，比如葡萄糖和氯離子。
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 in the next five years. The team of researchers also aims to adapt the device for environmental monitoring to measure heavy metals in the future.
研究人員還指出，目前他們研發的腕表比市場上流行的健身手表更大更重，戴起來不太舒服。因此，他們希望在未來五年內開發出適合市場需求的可穿戴式汗液傳感器。研究小組還打算在未來將該設備用于環境監測，進行重金屬測量等工作。
