The Bendable Electronics and Sensing Technologies group, has developed an ecological and efficient, wearable ultraviolet dosimeters. They can measure UV radiation and be safely disposed. Here’s more from Printed Electronics World:

Uncontrolled exposure to UV radiation is a major cause for skin cancer. The excess exposure could also damage the DNA of genes and hence the skin cell growth. The amount of UV radiation reaching on earth surface varies from region to region. The seasonal UV intensity fluctuations, radiation leaks and diverse geographical locations make UV detection quite challenging. Significant research efforts have been made for the development of portable UV sensors, with novel form factors including flexible and/or stretchable. Accordingly, many wearable and disposable consumer UV sensors have already been developed and are available in the market. However, disposability does not necessarily mean biodegradability, and this is where many of the reported devices fall short of expectations and do not fully address the growing issue of electronic waste (E-waste). Prof. Dahiya and co-workers present high performance disposable, wearable photodetectors having no adverse environmental impact during their fabrication as well as after the end of life.
