An In-Vitro Study of Wireless Inductive Sensing and Robust Packaging for Future Implantable Hydrogel-Based Glucose Monitoring Applications

Recent progress in conductive self‐healing hydrogels for flexible sensors

“…This study broadens the application of hydrogel sensors and provides implantable hydrogels with potential applications for glucose monitoring. For instance, Yu et al 5 developed a subcutaneous wireless implantable glucose sensor for glucose monitoring, as shown in Figure 14B. Besides, self‐healing hydrogels possessed applicability in various biosensing applications.…”

“…Compared to other traditional flexible materials, conductive hydrogels have broad application prospects in the field of wearable electronics due to their adjustable transparency, biomimetic structures and excellent biocompatibility. Taking advantages of their stimuli‐responsive electrical properties, conductive hydrogels can convert different external stimuli such as strain, 4 concentration, 5 temperature, 6 pH, 7 into detectable electric signals 8–10 . Therefore, conductive hydrogels have been widely installed in wearable sensing devices for motion recording and health monitoring.…”

Progress in hydrogels for sensing applications: a review

“…Prevention and constant self-control of glucose level in blood are essential tasks in order to get under control this pathology [76]. The majority of self-monitoring systems of blood glucose provides only point measurements without providing essential information such as glucose trend and daily peaks [77]. Because of this the demand for smart continuous glucose sensors has increased very much in the last years and interesting solutions involving hydrogelbased sensors have been proposed [78].…”
