At a macroscopic scale, hydrogels are solid polymers, which appear to have a higherstorage modulusthan their loss modulus, indicating the liquid characteristics at the molecular level and thus demonstrating aviscoelastic behavior. This distinctive feature makes them in various soft electronics, sensors,...
In this paper, we propose a highly sensitive and biocompatible glucose sensor using a semiconductor-based field effect transistor (FET) with a functionalized hydrogel. The principle of the FET device contributes to the easy detection of ionic charges with high sensitivity, and the hydrogel coated ...

Stretchable and tough PAANa/PEDOT:PSS/PVA conductive hydrogels for flexible strain sensors 2022, Materials Today Communications Citation Excerpt : Gao et al. fabricated an amylopectin/PVA hydrogel strain sensor with the gauge factor up to 4.96 under strains (200–500 %) [24]. Ho et al. designed...
for intensive insulin therapy for example, where inaccuracy at conditions of hypoglycemia could pose a very high risk to the patient. In addition, sensors based upon the enzyme glucose oxidase must have access to adequate oxygen to provide a linear glucose response. Sensor systems optimized for ...

for flexible sensors [143,150,151] and electrochemical biosensors [152]. Zhu et al. developed a DLP 3D printing method using PEDOT:PSS-PAAm as the conductive ink and poly(2-hydroxyethyl acrylate) as the insulating ink to print electroluminescent devices and capacitive sensors with a strong ...
Hydrogels are investigated broadly in flexible sensors which have been applied into wearable electronics. However, further application of hydrogels is restricted by the ambiguity of the sensing mechanisms, and the multi-functionalization of flexible sensing systems based on hydrogels in terms of cost, di...
Over the past two decades, there has been a surge of interest in hydrogel sensors and actuators because of their excellent biocompatibility, tunable mechanical and electrical properties. These functional hydrogels have been used for biomedical research [1–6], electronic skin [7–10] and other engi...
