低成本直接印刷技术在传感器的开发中发挥着重要作用，特别是在可弯曲和柔性传感器方面，解决了许多应用问题。本文沿着讨论了一种用低成本喷墨印刷工艺实现的电容式负载传感器的研制及其实验特性。负载传感器基于叉指（IDT）电容传感器，印刷在PET基板上，由介电层覆盖。相对于基于电阻应变传感器的传统解决方案提出的感测方法的特征在于不存在允许负载和应变之间的转换的机械，这通常由悬臂架构实现。实验结果提供了0.8 g的估计传感器分辨率。
Low cost direct printing technologies are assuming a terrific role for the development of sensors, with particular regards to bendable and flexible sensors addressing many applications. In this paper the development of a capacitive load sensor realized by low cost inkjet printing process is discussed along with its experimental characterization. The load sensor is based on a InterDigitated (IDT) capacitive Transducer, printed on a PET substrate, covered by a dielectric layer. The sensing methodology proposed as respect to traditional solutions based on resistive strain sensor is characterized by the absence of mechanics allowing the transduction between load and strain, which is usually implemented by cantilever architectures. Experimental results provide an estimated sensor resolution of 0.8 g.
