Stretchable and Low-Voltage Electrolyte Gate Organic Thin Film Transistors Based on Ionic Gel for Glucose Sensing

• • Operating voltage of −0.5 V and subthreshold slope of 98 mV dec−1 enable ultralow-power operation, critical for battery-limited wearable devices and reducing electrochemical side reactions. • • Mechanical robustness under 40% strain and after 10^4 stretching-releasing cycles ensures reliability in skin-mounted applications where cyclic deformation is unavoidable. • • Glucose sensing limit of detection (LOD) of 8.72 μM and limit of quantification (LOQ) of 29.08 μM, with linear range 100 μM to 1 mM (R² = 0.997), meets clinical thresholds for sweat glucose monitoring (typically 10–1000 μM). • • Long-term stability over 30 days without significant degradation addresses shelf-life and continuous operation requirements for disposable or reusable wearable sensors.
