Wireless, flexible, ion-selective electrodes (ISEs) are of great interest in the development of wearable health monitors and clinical systems. Existing film-based electrochemical sensors, however, still have practical limitations due to poor electrical contact and material–interfacial leakage. Here, we introduce a wireless, flexible film-based system with a highly selective, stable, and ...
The electrochemical sensors can also be developed as paper-based sandwich immunoassays on lateral flow test strips. An example of such a sensor is illustrated in Fig. ( Liu et al., 2014 ). Such sandwich immunoassays are suitable for the testing of large analytes with multiple antigenic sites, such as human chorionic gonadotropin ( Lu et al., 2005 ).

· July 15, 2002 - - Pittsburgh, PA - - Draeger has introduced a new electrochemical sensor, the DragerSensor XS-2 H2S for the measurement of H2S (hydrogen sulfide). This new sensor features better temperature and pressure compensation, reduced cross sensitivities, and a 2-year warranty. The patented three-electrode design of the DragerSensor XS-2 H2S sensor provides excellent specificity …
Electrochemical sensors are minimally affected bypressure changes. However, it is important to keep theentire sensor within the same pressure since differen-tial pressure within the sensor can cause sensor dam-age. Electrochemical sensors are also quite sensitiveto temperature and, therefore, the sensors are typi-cally internally temperature-compensated. However,it is better to keep the sample …
