BiOI: Self-Powered Humidity Sensor and Breath Monitor

Popis výsledku v původním jazyce

The self-powered, adaptable, quick, and precise humidity sensors are required to measure humidity in the microenvironment. Here, a simple one-step wet chemical method is presented to prepare stacked layered bismuth oxyiodide (BiOI) nanoplates. The remarkable response and self-powered behavior of BiOI nanoplates-based humidity sensors are demonstrated for the first time. The humidity sensing characteristics of BiOI are examined within the range of 30-80% relative humidity (RH) at an operating temperature of 323 K. The highest sensitivity level of 39 k Omega per %RH is determined for a relative humidity of 75.5%. A successful attempt is made to use this sensor as a human breathing process monitor. The sensor response times at room temperature in this test are 3.04(9) s at 0 V and 3.31(7) s at 20 V, whereas the recovery times are estimated to be 6.57(6) s at 0 V and 6.42(4) s at 20 V. Future advancements in sensing devices utilizing BiOI hold the potential to yield highly responsive, ultrafast sensors with simplified device geometries, and self-powered.
