The solution developed by engineers can upgrade wearable devices to health monitoring platform, which can measure molecular level information, so that people can more deeply understand the real-time situation of the body. The chemical components of sweat drops were collected and analyzed on the side of the adhesive film contacting the skin. The side facing the watch converts chemical signals into electrical signals, and reads, processes and displays them on the smart watch.
The team said they had eliminated the need for external connectors by using sensors made of double-sided tape and vertically conductive film. This makes the sensor easier to integrate with consumer electronics and eliminates the impact of motion on chemical data collection. Although engineers use custom smart watches, the technology can be applied to popular wearable device models.
