The sensor is called 'marine skin' and is designed to stick to the animal's skin or skin. It is said that when in the water, the weight of the sensor is approximately equal to the paper clip. The lightweight design allows the sensor to be used in various sizes. Marine animals wear without damaging their body or underwater behavior.
The tag was developed by the King Abdullah University of Science and Technology in Saudi Arabia. Scientists behind the label expect to have as many as 200 different marine species by the summer of 2019. The new label is non-intrusive, and old labels must be injected or used. Other invasive methods attach to animals.
These tags contain a one-year-old compact button cell. Scientists said that the prototype tag can continuously track seawater salinity, temperature and depth. In the prototype, the battery can last for five months without any optimization or data recording frequency changes. .
The tag's electronic components are mainly made of copper, tungsten, and aluminum, and use silicone as the main body of the skin. The cost of materials and processing for each sensor is less than US$12. The current prototype needs to connect to a smartphone to transmit data through Bluetooth. This is why the prototype is suitable for sharks in an aquarium in Spain. The second generation of sensors wants to transmit data wirelessly.
