从振动中收集能量为独立和可穿戴设备以及无线和远程传感的低能耗电子产品提供电力。在这篇文章中，提出了利用单管设计的紧凑型管状铁电驻极体能量收集器。这种单管收集器可以由壁厚分别为25和50 μm的市售氟化乙烯丙烯（FEP）管通过高温下的机械变形制造。它表明，所产生的功率是高度依赖于参数，如壁厚，负载电阻，和地震质量。在谐振频率约为80 Hz、输入加速度为1 × g（9.81 m s−2 rms）的情况下，使用80 g的地震质量，壁厚为25 μm的换能器可以达到300 μW的输出功率。
Energy harvesting from vibrations provides power to low‐energy‐consuming electronics for standalone and wearable devices as well as for wireless and remote sensing. In this contribution, compact tubular ferroelectret energy harvesters utilizing a single‐tube design are presented. Such single‐tube harvesters can be fabricated from commercially available fluorinated ethylene propylene (FEP) tubes with wall thicknesses of 25 and 50 μm, respectively, by mechanical deformation at elevated temperature. It is demonstrated that the generated power is highly dependent on parameters such as wall thickness, load resistance, and seismic mass. Utilizing a seismic mass of 80 g at resonance frequencies around 80 Hz and an input acceleration of 1 × g (9.81 m s−2 rms), output powers up to 300 μW can be reached for a transducer with 25 μm thick walls.
