针对气动气球致动器(PBAS)微器件的优化设计问题，提出了气球纵向分离结构的设计思想。我们进行了基于有限元的模拟，并验证了其在计算和表征PDMS(聚二甲基硅氧烷)材料制备的PBA弯曲运动方面的适用性。在本研究中，通过模拟表明，随着气球分割的数量的增加，弯曲特性可以显著改变。此外，实验表明，采用这种设计可以减小气球膨胀的幅度，以便在比同等尺寸的单个气球结构所需的更紧凑的空间内实现所需的弯曲运动。
Toward optimum design of micro devices using pneumatic balloon actuators (PBAs), we propose a design concept with longitudinally-divided balloon structure. We have performed FEM-based simulation and demonstrated its applicability to compute and characterize the bending motion of PBAs fabricated from PDMS (polydimethylsiloxane) material. In the present study, it is shown through the simulation that the bending characteristics can be significantly altered dependent on the number of balloon divisions. Moreover, it is experimentally indicated that, with the present design, the magnitude of the balloon inflation can be reduced so as to achieve a desired bending motion in more compact space than required with a single-balloon structure of the equivalent size of the balloon.
