The development is a lightweight touch sheet that is equipped with a flexible resistive sensor and
The device is coated on top with a superhydrophobicpolydimethylsiloxane (PDMS) silicone sheet, which is impregnated with graphene and additionally processed by a laser. Due to this, water droplets are repelled from the sensor, which ensures its durability and stability. Laser texturing allows you to constantly monitor and measure the behavior of water droplets, whether they remain, glide, bounce or split on the sensor surface.
The study showed that placing the sensor underdifferent angles, does not affect the reliability of the results obtained. Therefore, the sensor can be easily attached to a wide variety of objects such as an umbrella, car or house.
Although there is still much to be doneto increase accuracy of the device, the sensor is expected to become the basis for next-generation weather sensing. Scientists believe that if this technology were widely adopted, it could be possible to obtain massive data that would allow the development of local weather maps in real time.
Disasters are being reported all overworld, and one source of serious damage to cities is flooding caused by localized heavy rainfall. Sharing local weather information can save lives. However, collecting local weather information in real time is difficult because such data collection requires bulky and expensive sensors. The development, the researchers hope, will help solve this problem.
