摘要

人体循环系统可储存高浓度的氧气,并持续、同步地向数以万亿计的细胞提供氧气,而每个细胞都无需接触周围环境。受生物循环系统的启发,我们设想未来的机器人系统将具备多功能、完全集成、可充电的空气能量输送和储存系统。我们提出了一种具有高氧气溶解度的水性空气阴离子乳液(ACE),它可以完全从溶解氧中获取能量。与纯 KOH 样品相比,ACE 的硅油含量仅为 20%,其溶解氧储存量是纯 KOH 样品的两倍(15 毫克/升),可保持稳定数月,并显示出更优越的氧还原反应动力学。完全浸没电极的锌-空气流动池可以在 5.6 mA/cm2 的条件下达到 4.6 mW/cm2。一种多功能致动器流动电池配置将 ACE 同时用作液压致动器和储能流体,证明了 ACE 作为软机器人系统多功能、灵活电源的可行性。

Emulsions that store oxygen for fast ORR kinetics and multifunctional robotic and mobility systems
Human circulatory systems store large concentrations of oxygen and provide it continuously and simultaneously to trillions of cells without the need for each cell to access the surrounding environment. Inspired by biological circulatory systems, we envision future robotic systems with multifunctional, fully integrated, air-rechargeable energy delivery and storage. We present an aqueous air catholyte emulsion (ACE) with high oxygen solubility that can derive energy entirely from dissolved oxygen. With only 20% silicone oil by volume, ACEs can store twice as much dissolved oxygen (15 mg/L) as pure KOH samples, remain stable for several months, and show superior oxygen reduction reaction kinetics compared to KOH. Zinc-air flow cells with fully submerged electrodes can achieve 4.6 mW/cm2 at 5.6 mA/cm2. A multifunctional actuator flow cell configuration employs an ACE as both a hydraulic actuator and an energy storage fluid, demonstrating the feasibility of ACEs as multifunctional, flexible power sources for soft robotic systems.
