Conductive adhesives

Definition

Conductive adhesives are specialized bonding materials that possess the ability to conduct electricity while providing adhesion between surfaces. These adhesives are essential in applications where traditional soldering or wiring methods are impractical, particularly in the integration of electronic components with flexible substrates, such as those found in smart textiles and e-textiles. Their unique properties make them suitable for creating connections in devices that require flexibility and lightweight solutions.
