Non-invasive Glucose Detection Wearable Sensor

People with diabetes often need to monitor blood glucose levels regularly to maintain treatment records or regulate eating habits. Traditional monitoring techniques are invasive which require frequently finger pricking and normally restricted to one kind of glucose sensing scenarios. A new type of wearable non-invasive glucose biosenor is developed by using flexible fabric organic electrochemical transistor. With in situ amplification of target analyte signal in solution, the biosenor can be used to detect glucose in different sensing scenarios, such as saliva, sweat and tear.

This wearable sensor has excellent bending stability, high sensitivity (down to 30 nM glucose concentration) and good selectivity due to the utilization of material engineering, electrochemical engineering and enzyme modification method during sensor fabrication. The real time and long term reliable monitoring of glucose level in body fluids can be realized by wireless detection platform so that better diabetic management can be provided to needed patients.

This technology will be a revolution towards traditional blood glucose meter and can be expanded to different healthcare monitoring systems.
