多年来，微力传感技术的研究和开发已经获得了很大的牵引力，特别是对于微机器人应用，如微操作和生物医学材料表征研究。此外，近年来，已经开发了新的微制造技术，例如双光子聚合（2PP），其能够实现快速原型制作、高分辨率特征和广泛材料的利用。在这项工作中，这两个领域相结合，实现了第一个完全3D打印的基于视觉的微力传感器。该传感器具有可调的刚度特性，这是模拟和校准值的各种2PP打印设置进行比较。此外，一种新的双材料印刷方法被用来制造传感器具有高度顺应性的传感结构和刚性体。最后，传感器被用来测量作为细胞模拟的鱼卵的机械特性，以展示该系统的可能应用。
Over the years, research and development into micro-force sensing techniques has gained a lot of traction, especially for microrobotic applications, such as micromanipulation and biomedical material characterization studies. Moreover, in recent years, new microfabrication techniques have been developed, such as two-photon polymerization (2PP), which enables fast prototyping, high resolution features, and the utilization of a wide range of materials. In this work, these two fields are combined to realize the first fully 3D printed vision-based micro-force sensor. The sensor exhibits tunable stiffness properties, which are simulated and compared with calibration values for a variety of 2PP printing settings. Furthermore, a novel bimaterial printing approach was utilized to fabricate sensors with a highly compliant sensing structure and rigid body. Lastly, the sensors are used to measure the mechanical properties of fish eggs as a cell analog to showcase the possible applications of the system.
