Individual warning systems using electric signals


 

Overview

A number of workplaces have inherent dangers that need to be minimized using warning systems. Currently available acoustic or optic methods can be compromised by interference from the environment.

Aims of the project are to establish perception thresholds for electric stimulation of the skin and to develop a reliable electric warning system.

In a population of volunteers, we will determine the perception thresholds for different electric stimulation paradigms at a number of positions on the body at rest and under disturbances from the environment. The results will inform the development of a wearable electric warning system. Innovative textile electrode materials will be utilized that can be integrated in clothing.

The data and findings of this study can serve as a basis for establishing a standard for the electric stimulation of the skin as a danger warning signal. Electric warning methods can increase the safety in dangerous workplaces, either as an alternative to other warning methods or in combination.
