Topic: Risk, prevention and care in population studies
ABSTRACT Flexible and wearable electronics are attracting surging attention due to their potential applications in human health monitoring and precision therapies. Safety hazards including strong magnetic field and electric leakage are big risk factors for human health. It remains challenging to develop self‐powered and wearable safety hazard sensors that could not only be able to monitor human motions but also have functions for detecting potential hazards. In this work, we fabricated a self‐powered, shapeable, and wearable magnetic triboelectric nanogenerator (MTENG) based on ferrofluid, Ecoflex, and carbonized silk fabric that possessed effective hazard prevention and biomechanical motion sensing ability. A peak open‐circuit voltage of 0.7 V and short‐circuit current of 10 μA m −2 can be achieved when magnetic field is changed between 3.5 and 37.1 mT. As a component of triboelectric layer of the MTENG, ferrofluid can substantially extend the range of its sensing capabilities to many hazardous cues such as dangerous magnetic field. Furtherly, the developed multifunctional and self‐powered sensor can be used to monitor human activities such as drinking water and bending finger. This effort opens up a new design opportunity for hazard avoidance wearable electronics and self‐powered sensors.

Why it matters
This paper describes a wearable sensor for detecting hazards such as magnetic fields and for monitoring body movements, and does not address Alzheimer's disease. It provides no information on treating, curing or preventing Alzheimer's disease.

Study details
- Evidence strengthLow
How this study scored 43/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on senior author's track record, so that was left out: it earned 41 of the 96 points we could judge it on, which is 43 out of 100.
