Promising power source for wearable electronics

Flexible and stretchable power sources for wearable electronics

Flexible and stretchable power sources represent a key technology for the realization of wearable electronics. Developing flexible and stretchable batteries with mechanical endurance that is on par with commercial standards and offer compliance while retaining safety remains a significant challenge. We present a unique approach that demonstrates mechanically robust, intrinsically safe silver-zi...

Wearable Magnetic Field Sensors for Flexible Electronics

Highly flexible bismuth Hall sensors on polymeric foils are fabricated, and the key optimization steps that are required to boost their sensitivity to the bulk value are identified. The sensor can be bent around the wrist or positioned on the finger to realize an interactive pointing device for wearable electronics. Furthermore, this technology is of great interest for the rapidly developing ma...

Posture Correction with Wearable Electronics

Wearable electronics technology has become very popular in recent years, and it is advancing. An important application of this technology is in health monitoring. I present an application of wearable electronics for posture correction, utilizing inertial sensors attached to certain parts of clothing. When bad posture is detected, the wearer is notified. Posture data can be collected by a nearby...

The Challenges of Wearable Electronics

Lifetime Aspects of Wearable Electronics

In the course of two European projects the endurance behavior of stretchable electronic substrates and of electronic textiles was investigated. The results have to a large extent been published already. In this work new analyses to the earlier results are presented. Straightforward analytical approaches are used to describe fatigue under cyclic mechanical loading in the two technologies. For st...
