Recent Developments of Flexible and Stretchable Electrochemical Biosensors.

摘要: The skyrocketing popularity of health monitoring has spurred increasing interest in wearable electrochemical biosensors. Compared with the traditionally rigid and bulky biosensors, flexible stretchable devices render a unique capability to conform complex, hierarchically textured surfaces human body. With recognition element (e.g., enzymes, antibodies, nucleic acids, ions) selectively react target analyte, biosensors can convert types concentrations chemical changes body into electrical signals for easy readout. Initial exploration integrates electrodes on textile thin-film substrate materials. A property is needed device form an intimate contact skin surface deform various natural motions. Thus, materials structures have been exploited ensure effective function biosensor. In this mini-review, we summarize recent development including their principles, representative application scenarios saliva, tear, sweat, interstitial fluid), structures. While great strides made challenges still exist, which represents small fraction opportunities future burgeoning field.
