Reversible contacting of smart textiles with adhesive bonded magnets

Abstract

The aim of this study was to develop a reversible electrical contacting through adhesive bonded neodymium magnets. To implement this, suitable magnets and adhesives are chosen by defined requirements and conductive bonds between textile and magnet are optimized. For the latter, three different bonds are produced and tested in terms of achievable conductivity and mechanical strength. It is shown that gold-coated neodymium magnets are most appropriate for such a contact. The reproducible electrical resistances are low with sufficient mechanical strength.
