Logicink, a San Francisco-based company, markets day-long 'tattoos' to measure the sun's ultraviolet dose on the skin, alerting people to the risk of burns and reducing the dangers associated with sun exposure, such as certain skin cancers. The company also offers temporary tattoos to assess a person's hydration level at rest or during exercise and prevent the risks associated with dehydration. This solution could be of particular interest during training and matches to ensure the hydration level of each player and to develop hydration strategies adapted to climatic and atmospheric conditions.
