The pH of wound fluid has long been recognized as an important diagnostic for assessing wound condition, but as yet there are few technological options available to the clinician. The availability of sensors that can measure wound pH, either in the clinic or at home could significantly improve clinical outcome - particularly in the early identification of complications such as infection. New material designs and electrochemical research strategies that are being targeted at wound diagnostics are identified and a critical overview of emerging research that could be pivotal in setting the direction for future devices is provided.
