Unaware fatigue causes inefficiencies and unsafe behaviors. Therefore, an easily-used technique to monitor labor intensity is critical. In this work, the humidity-sensitive material Cs3Cu2I5 was used to monitor breath and grade labor intensity without contact. The Cs3Cu2I5 showed reversible conversion to the CsCu2I3 phase by being exposed to water. EMI-TFSI was added to improve the material's conductivity and electrochemical stability, helping to passivate surface defects and adjust the response sensitivity. Further mechanism explanation was explored by density functional theory calculation and electrochemical impedance spectroscopy. Switching from 40 % RH to 90 % RH, the sensor resistance changed by 161.3 megohms with a relative change ratio of 0.967. Besides, the sensor has a short response/recovery time (e.g., 2.0/0.5 s switching from 40 % RH to 60 % RH), with good repeatability and stability in high humidity. Then, the developed high-performance lead-free sensor was integrated ....
Just when you thought our masked days were (kinda) over, in comes news of a potential haze. Boo hoo. In a statement on May 30, 2023, the Meteorological Service Singapore (MSS) projected the occurrence of El Niño conditions and a positive Indian Ocean Dipole (IOD) in the latter half of 2023. What this means is warmer and drier weather conditions. ....
The device will gather health metrics from breath and pressure readings in much the same way that Fitbits and Apple Watches track movement and sleep. ....
