随着绿色和可持续发展理念的广泛采用，提高柔性压力传感器的传感性能，同时降低制造成本和环境污染已成为紧迫的研究问题。我们从天然绿色植物竹子中汲取灵感，采用原生竹浆作为生产抽纸的原材料。由此产生的竹筒结构用作介电层。我们提出了一种成本极低、用户友好且可持续的折纸方法来制造纸基传感器。通过有限元模拟和实际实验对传感器的结构参数进行了深入研究和优化。该传感器的显着特点包括高灵敏度（0-50 kPa 范围内为 1.96 kPa ^–1）、低检测限 (2 Pa)、宽压力检测范围 (0-500 kPa)、快速响应和恢复时间（40 和 45 ms，分别），以及可靠的耐用性和稳定性（∼5000 次循环）。实验结果表明这些传感器在人体运动、健康监测和人机交互等领域的成功应用。传感器的潜在应用扩展到柔性可穿戴设备、智能医疗、人机协作和电子皮肤（e-skin）。

Bamboo-Inspired, Environmental Friendly PDMS/Plant Fiber Composites-Based Capacitive Flexible Pressure Sensors by Origami for Human–Machine Interaction

With the widespread adoption of green and sustainable development concepts, enhancing the sensing performance of flexible pressure sensors while reducing manufacturing costs and environmental pollution has emerged as a pressing research issue. Drawing inspiration from bamboo, a naturally occurring green plant, we utilized virgin bamboo pulp as the raw material for producing draw paper. The resulting bamboo cylinder structure serves as the dielectric layer. We propose an extremely low-cost, user-friendly, and sustainable origami method for fabricating paper-based sensors. The structural parameters of the sensor were thoroughly investigated and optimized through finite element simulations and practical experiments. Notable features of the sensor include high sensitivity (1.96 kPa^–1 within 0–50 kPa), a low detection limit (2 Pa), a wide pressure detection range (0–500 kPa), rapid response and recovery times (40 and 45 ms, respectively), and reliable durability and stability (∼5000 cycles). Experimental results demonstrate the successful application of these sensors in areas such as human motion, health monitoring, and human–computer interaction. The potential applications of sensors extend to flexible wearables, smart healthcare, human–machine collaboration, and electronic skin (e-skin).
