摘要

This paper details the development of screen printable networks of sensors and connections on textiles for medical applications. A polyurethane paste is screen printed on to a woven textile to create a smooth, high surface energy interface layer. A silver paste is subsequently printed on top of this interface layer to provide a conductive track. The silver track is then encapsulated with another layer of polyurethane paste so that the silver track is protected from abrasion and creasing. The resulting printed structure has a maximum width of 4mm and is 200-350 μm high. The effect of increasing the thickness of the encapsulation layer and changing the track width are examined using a mandrel test and machine washing. The fully encapsulated track is washed at 40 ℃ with detergent. The most durable track structures can last more than 10 washes before becoming open circuit. The durability is limited by the water absorption and brittle properties of the cured polyurethane, contributing to brittle failure.
