已经证明了两种工作模式的工作特性：(1)工作在自重(等张工作)下；(2)工作在恢复弹簧上。重要的是，分析中考虑了电刺激对致动器材料弹性模量的影响。结果表明，弹性模数的变化对驱动器的应变和每循环功有显著影响。计算了每种情况下每个周期的最大工时。根据我们的理论预测和其他已发表的模型，对不同材料进行了比较。加载方式对每循环做功有很大影响。
Work-per-cycle calculations have been demonstrated for two modes of actuation behaviour: (1) working against a dead weight (isotonic actuation) and (2) working against a restoring spring. Importantly, the influence of the electrical stimulus on the elastic modulus of the actuator material has been included in the analysis. The change in elastic modulus is shown to significantly influence the actuator strain and work-per-cycle. The maximum work-per-cycle for each case has been calculated. Comparison of different materials has been made on the basis of our theoretical prediction and other published models. Work-per-cycle is shown to be significantly affected by the mode of loading.
