Microstructure construction is a common strategy for enhancing the sensitivity of flexible pressure sensors, but it typically requires complex manufacturing techniques. In this study, we develop iontronic sensor (FIPS) by embedding an isolated three-dimensional network spacer (3DNS) between ionic gel and Ti3C2Tx MXene electrode, thereby avoiding microstructure By leveraging substantial deformation 3DNS high capacitance density resulting from electrical double layer effect, exhibits (87.4 kPa–1) over broad high-pressure range (400–1000 kPa) while maintaining linearity (R2 = 0.998). Additionally, FIPS demonstrates rapid response time 46 ms, low limit detection at 50 Pa, excellent stability 10 000 cycles under 600 kPa. As practical demonstrations, can effectively monitor human motion such as elbow bending assist robotic gripper in accurately sensing gripping tasks. Moreover, real-time, adaptive 7 × array system built recognize both numeric alphabetic characters. Our design philosophy be extended fabricating sensors with performance without involving techniques, facilitating applications monitoring, tactile sensing, human–machine interaction.

Abstract Dopamine (DA) is a neurotransmitter secreted by the brain that plays variety of roles in central nervous system. An imbalance dopamine can cause range disease symptoms and negative effects, such as Parkinson's arrhythmia. Detecting DA accurately rapidly therefore crucial for medical diagnosis prevention. In this study, PVP rGO-MWCNT were encapsulated using hydrothermal method to form composite material. The was then characterized scanning electron microscopy (SEM). three materials combined, based on this, new electrochemical sensor constructed. It worth noting high specific surface area conductivity cooperate with amphiphilic stable dispersion PVP, which further improves performance DA. Under optimal conditions, content detected within wide low detection limit explained redox process sensor. addition, shows satisfactory recovery accuracy detecting real human serum samples standard addition method.
