The electronic tattoo, or E-tattoo, can monitor people's electrodermal activity, showing that they may be feeling uncomfortable or stressed. The tattoo is placed on the palm of the individual's hand and connected to a smartwatch. The tattoo is the great novelty developed by the researchers. Check below other curious information about how the e-tattoo works:

Curiosities about how the e-tattoo works, the tattoo developed by researchers
Did you know that the palm of your hand is the part of your body that says a lot about your emotional state? Sweat, for example, can show when a person is nervous, anxious or very excited.
Based on this information, researchers at the University of Texas at Austin and Texas A&M University, have associated Electronic Tattoo technology with “electrodermal activity” or “detection of EDA”.
Recently, an article was published in a magazine called Nature, in which the researchers inform that they developed this e-tattoo based on a graphene.
Graphene is a type of material taken from graphite and is used in technology because it has physical properties that serve technological applications. This material is placed in the palm of the hand and is barely noticeable.
How is graphene applied?
This has been the darling among researchers because of its thickness, in addition it has a quality excellent when it comes to measuring the electrical potential of the human body, accurately making the monitoring. However, it has been challenging to use the material as they are ultra-thin and can't take a beating. That is, if there is a lot of movement in the applied area, it can be damaged.
Find out where the inspiration for this project came from
Believe it or not, but the e-tattoo was inspired by virtual reality, games and metaverse.
Nanshu Lu, project leader and professor at the Department of Aerospace Engineering and Mechanical Engineering at university of texas, has been working with his team on this project for years.
His intention with the project is to reduce the social stigma of people who need to use sensors to monitor their health. What happens is that the technology currently used to monitor the palm of the hand is usually visible and does not make an accurate reading.
