Abstract

Disclosed herein are embodiments of methods of inspection and manufacture of flexible printed circuit boards and flexible sensor sheets, and apparatuses such as wound dressing components utilizing the same. The methods can comprise applying a coating material to a flexible printed circuit board, wherein the coating material comprises a material that will fluoresce when exposed to UV or visible light and the flexible printed circuit board comprises one or more electronic components. The coated flexible printed circuit board can be positioned under UV or visible light to cause the coating material to fluoresce.

Claims4

Dependent claims

A flexible sensor sheet for use on a wound, comprising:

a flexible substrate;
electronic components including one or more sensors positioned on the flexible substrate for detecting wound characteristics;
and
a first material coated on a first portion of the flexible substrate, wherein the first material is configured to fluoresce when exposed to UV or visible light and a second material coated on a second portion of the flexible substrate, wherein the second material is configured to fluoresce when exposed to UV or visible light, wherein the first material is different than the second material;
and
wherein the first material is a non-extensible material and the second material is an extensible material.
