Researchers have developed a highly sensitive UV sensor with spectral selectivity. The ultra-low power consumption architecture of the UV index sensor can help users achieve a thinner wearable design with smaller batteries, and the average current is as low as 1.2 at a UV measurement rate of once per second μ A. The battery life is effectively prolonged

a new study introduces a new manufacturing method of a low-cost, high-sensitivity sensor for detecting ultraviolet radiation (UVR) with naked eyes. This paper-based wearable sensor allows users to monitor the impact of UVR in daily life

uvr can be divided into UVA, UVB and UVC according to wavelength. To monitor the effects of different ultraviolet (UV) radiation, low-cost spectral selective UV sensors are needed. However, due to the high cost and complex manufacturing process, it is difficult to realize large-scale deployment of the current sensor 10 and lower fixture, which adopts ball screws and FM electromechanical pullers

Vipul Bansal and colleagues from Royal Melbourne University of technology in Australia designed a highly sensitive UV sensor with spectral selectivity. 80% of his design secret is to create a kind of invisible ink based on polyoxometalate. This kind of ink has the special performance of spectral selective UV sensing. When combined with low-cost ready-made components (such as filter paper, transparent film or pen), it can produce a paper-based low-cost wearable UV sensor

in a recent article published in nature communications, researchers demonstrated the applicability of this new technology through a customized paper-based smiley face UV sensor. The sensor can apply pressure to six different skin types with 10kN clamping force around, and monitor the maximum allowable exposure threshold of each UVR since the establishment of the company. This result shows that spectral selective UV sensors may have the potential to be put into mass production and customized for specific skin types
