【摘要】 智能化社会需要数以万计的分布式传感器，利用电池进行供能有一定的局限性。针对分布广泛的传感器网络终端节点的供能问题，一种有潜力的方案是收集环境中的能源，因地制宜地为微纳系统供能。提出了一种磁支持式的接触分离模式混合发电机，该混合发电机以磁铁对代替传统的弹簧支持结构，并在纳米发电机的基础上引入电磁线圈，形成混合发电机。相比于弹簧支持式纳米发电机，磁支持式在相同能量的外部激励下能够输出更大的电压和电流，纳米发电机和电磁发电机具有完全不同的发电特性和基本相当的发电能力。综上，相比于弹簧支持式纳米发电机，磁支持式具有更强的低能量机械能拾取能力，在磁支持式纳米发电机的基础上形成的混合发电机能够大幅增加发电机整体输出能力。更多还原

【Abstract】 An intelligent society requires tens of thousands of distributed sensors, and the use of batteries for energy supply has certain limitation. Aiming at the energy supply problem of widely distributed sensor network terminal nodes, a potential solution is to collect energy in the environment and provide energy for the micro-nano system. A magnetically supported contact-separation mode hybrid generator is proposed in this paper, the hybrid generator replaces the spring support structure of the traditional contact-separation mode generator with magnet pairs, so electromagnetic coils can be introduced on the basis of contact-separation mode nanogenerators to form a hybrid generator. Compared with spring supported mode nanogenerator, the magnetically supported contact-separated mode nanogenerator can output larger voltage and current under the same external excitation with the same energy. Magnetically supported nanogenerators and electromagnetic generators have completely different power generation characteristics and have basically equivalent power generation capabilities. In conclusion, compared with spring supported mode nanogenerator, the magnetically supported contact-separated mode nanogenerator has stronger low-energy mechanical energy pickup capability. The hybrid generator formed on the basis of the magnetically supported nanogenerator can greatly increase the overall output capacity of the generator.更多还原
