Skin-contact wearable electrochemical biosensing tools: A perspective for the wellbeing of neurological patients

Neurological Disorders (NDs) have become more prevalent with the increase of life expectancy. Wearable devices are particularly appealing for NDs since they would strongly facilitate the continuous health status monitoring in people that are not capable of communicating their needs or discomfort. This review summarizes the studies over the past five years reported in the literature regarding sampling and biosensing solutions for the development of wearable electroanalytical platforms. Our survey is mainly focused on skin-contact wearable biosensors, with a special emphasis on sweat sampling and analysis using biocompatible materials. Examples of devices for monitoring chemical parameters involved in the wellbeing of ND patients are discussed.
