Wearable sensor for continuous analysis of sweat

03.10.2023

Continuous monitoring of sweat can reveal valuable information about human health, such as the body’s glucose levels. However, wearable sensors previously developed for this purpose have been lacking, unable to withstand the rigors or achieve the specificity needed for continuous monitoring. Now, the research team has created a novel wearable patch that may be up to the task.

What can AI do in laser materials processing?

30.08.2023

Automation and zero-defect production are important trends in machine construction. Artificial intelligence (AI) plays a major role in advancing both of them. Today, it can already detect deviations in process monitoring data and implement quality control in real time. In the future, AI will regulate many more processes and simplify process planning through assistance functions.

Product safety: anti-counterfeiting through laser printing

15.06.2023

A team of researchers at the Max Planck Institute of Colloids and Interfaces (MPICI) has developed a method that could make it more difficult to counterfeit products in the future. The new and patented method makes it possible to produce unique, non-copyable fluorescent patterns quickly, environmentally friendly and at low costs.
