| 1 | Zero-waste emission design of sustainable and programmable actuators显示文摘Moisture-responsive actuators are widely used as energy-harvesting devices due to their excellent ability to spontaneously and continuously convert external energy into kinetic energy.However,it remains a challenge to sustainably synthesize moisture-driven actuators.Here,we present a sustainable zero-waste emission methodology to prepare soft actuators using carbon nano-powders and biodegradable polymers through a water evaporation method.Due to the water solubility and recyclability of the matrixes employed here,the entire synthetic process achieves zero-waste emission.Our composite films featured strong figures of merit and capabilities with a 250◦maximum bending angle under 90%relative humidity.Programmable motions and intelligent bionic applications,including walkers,smart switches,robotic arms,flexible excavators,and hand-shaped actuators,were further achieved by modulating the geometry of the actuators.This sustainable method for actuators’fabrication has great potential in large-scale productions and applications due to its advantages of zero-waste emission manufacturing,excellent recyclability,inherent adaptive integration,and low cost. | Linchao Sun Lixuan Che Ming Li William George Neal Xu Leng Yaojia Long Yifeng Jia Yunhu Gao Matteo Palma Yao Lu | 2023 | SusMat2023，3，2： | 0 |
| 2 | A nanonewton-scale biomimetic mechanosensor显示文摘Biomimetic mechanosensors have profound implications for various areas,including health care,prosthetics,human‒machine interfaces,and robotics.As one of the most important parameters,the sensitivity of mechanosensors is intrinsically determined by the detection resolution to mechanical force.In this manuscript,we expand the force detection resolution of current biomimetic mechanosensors from the micronewton to nanonewton scale.We develop a nanocrack-based electronic whisker-type mechanosensor that has a detection resolution of 72.2 nN.We achieve the perception of subtle mechanical stimuli,such as tiny objects and airflow,and the recognition of surface morphology down to a 30 nm height,which is the finest resolution ever reported in biomimetic mechanosensors.More importantly,we explore the use of this mechanosensor in wearable devices for sensing gravity field orientation with respect to the body,which has not been previously achieved by these types of sensors.We develop a wearable smart system for sensing the body’s posture and movements,which can be used for remote monitoring of falls in elderly people.In summary,the proposed device offers great advantages for not only improving sensing ability but also expanding functions and thus can be used in many fields not currently served by mechanosensors. | Chi Zhang Mengxi Wu Ming Li Lixuan Che Zhiguang Tan Di Guo Zhan Kang Shuye Cao Siqi Zhang Yu Sui Jining Sun Liding Wang Junshan Liu | 2023 | Microsystems & Nanoengineering2023，9，4： | 0 |
