薄的、低成本的、柔性的并且与商业微电子芯片兼容的力传感器对于在生物医学感测、精密手术和机器人中的使用具有极大的兴趣。通过利用微流体和电容传感的组合，我们开发了一种薄，灵活的力传感器，是一致的和强大的。该传感器由一个由可变形材料制成的部分填充的微流体通道组成，该通道覆盖一系列涂有薄绝缘聚合物层的叉指电极。当力施加到微流体通道储存器时，流体在电极上沿通道沿着移位，从而引起与所施加的力成比例的电容变化。微流体模具本身由通过气溶胶喷射印刷沉积的低成本牺牲材料制成，气溶胶喷射印刷也用于印刷电极层。我们设想了一个大范围的工业和生物医学应用这种力传感器。基于微流体技术的高度灵活的电容式力传感器对作用力的线性电容响应通过气溶胶喷射打印实现低成本和鲁棒力传感器的快速原型设计可针对各种灵敏度和力测量范围进行可调设计Jing et al.报道了一种基于微流体和电容感测的组合的薄的、适形的力传感器。低成本传感器通过气溶胶喷射印刷制造，并显示出高度线性的响应，可调的灵敏度和力范围的可调设计参数。
Force sensors that are thin, low-cost, flexible, and compatible with commercial microelectronic chips are of great interest for use in biomedical sensing, precision surgery, and robotics. By leveraging a combination of microfluidics and capacitive sensing, we develop a thin, flexible force sensor that is conformable and robust. The sensor consists of a partially filled microfluidic channel made from a deformable material, with the channel overlaying a series of interdigitated electrodes coated with a thin, insulating polymer layer. When a force is applied to the microfluidic channel reservoir, the fluid is displaced along the channel over the electrodes, thus inducing a capacitance change proportional to the applied force. The microfluidic molds themselves are made of low-cost sacrificial materials deposited via aerosol-jet printing, which is also used to print the electrode layer. We envisage a large range of industrial and biomedical applications for this force sensor. Highly flexible, capacitive force sensors based on microfluidics Linear capacitance response to applied force Rapid prototyping of low-cost and robust force sensors via aerosol-jet printing Tunable design for various sensitivities and force measurement ranges Jing et al. report a thin, conformable force sensor based on a combination of microfluidics and capacitive sensing. The low-cost sensor is fabricated via aerosol-jet printing and shows a highly linear response with adjustable design parameters for tunable sensitivities and force ranges.
