Hooray, Graphene Biosensing Tattoos Are Here!

The wait is almost over. We are getting very excited! The benefits consist of using a new thing as opposed to the old thing, a robust and steady supply of medical data to the data hoarders, and new profits for the investors. The side effects are worth it. 

How does it work? Here is how it works for now. 

The device takes its measurements by shooting an electrical current into the skin and then analyzing the body’s response, which is known as bioimpedance. There is a correlation between bioimpedance and changes in blood pressure that has to do with blood volume changes. However, the correlation is not particularly obvious, so the team had to create a machine learning model to analyze the connection to get accurate blood pressure readings.
