摘要

结合织物微结构（∝p3 /3接触面积）和离子膜（∝P2/3离子调制）的仿生双机制传感器，灵敏度为242 kPa−1，线性度为0.997 (0-1 MPa)， LSF为242,000。通过智能鞋垫进行的医疗级验证显示了1.8%的GRF误差（非线性传感器为6.5%），从而实现了精确的早期骨折风险预测，并验证了医疗级可穿戴设备。

Skin-Inspired Ultra-Linear Flexible Iontronic Pressure Sensors for Wearable Musculoskeletal Monitoring

Highlights

Bioinspired dual-mechanism sensor combining fabric microstructures (∝ P^1/3 contact area) and ionic film (∝ P^2/3 ion modulation) achieves 242 kPa⁻¹ sensitivity with 0.997 linearity (0–1 MPa), yielding record LSF of 242,000.
Medical-grade validation via smart insole demonstrates 1.8% GRF error (vs. 6.5% in nonlinear sensors), enabling precise early fracture-risk prediction and validating medical-grade wearables.

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
