Medical News Today -- In the future, more and more products will be able to interpret what users are feeling and use that information in a smart way. To illustrate the power of this theory, researcher Miguel Bruns Alonso has developed a pen which can measure the stress levels of the person using it, and can actually help to reduce that stress. In experiments, the heart rate of people who used the anti-stress pen fell by an average of five percent. On Wednesday, 23 December, Miguel Bruns Alonso will receive his PhD degree from TU Delft based on his research into this subject.
