Recent pilot studies have focused on developing wearable biosensors for non-invasive monitoring of our health using fashionable and easy to adorn items of clothing.
Most biosensors aim to solve common ailments such as diabetes, lactic acidosis, and hyponatremia. This work aims to detect glucose, lactate and sodium levels of the wearer using a microfluidic device. The device is designed to be attached to the nose pad of the glasses, where it collects sweat through the inlet of the device. Sweat is easily accessible and comprises different analytes such as ions, alcohols, drugs and heavy metals; making it an ideal biofluid to be analysed . Herein, the sweat travels to the sensors placed close to the inlet, where biomarker levels are detected, measured and evaluated.
