Abstract

Drawing inspiration from nature by exploring bionic micro-nano structures found in animals and plants offers an effective strategy for enhancing the sensing performance of flexible sensors in emerging applications. This paper reviews recent advances in bio-inspired micro-nano structures of flexible sensors, spanning surface architecture to interface engineering. Firstly, two primary directions of animal-inspired designs, including spiders, scorpions, and tree frogs, and plant-inspired designs, including flytraps, mimosas, and nepenthes, are introduced to establish the relationship between micro-nano structures and sensing properties. Secondly, the cutting-edge progress of bio-inspired geometries in flexible pressure sensors, such as pyramids and hemispheres, are reviewed to enhance the force-sensitive signals in flexible sensor. Thirdly, the efficient implement of bionic structures including cracks, wrinkles, serpentines and helices, as well as interface engineering is then emphasized, with a focus on improving sensing performance under complex deformations in practical scenarios. Finally, the key challenges and future prospects in the manufacturing of bio-inspired micro- and nanostructured flexible sensors are discussed, illustrating the great potential of this method in fields such as health monitoring and human-machine interfaces.

期刊介绍： Sensors and Actuators A: Physical brings together multidisciplinary interests in one journal entirely devoted to disseminating information on all aspects of research and development of solid-state devices for transducing physical signals. Sensors and Actuators A: Physical regularly publishes original papers, letters to the Editors and from time to time invited review articles within the following device areas: • Fundamentals and Physics, such as: classification of effects, physical effects, measurement theory, modelling of sensors, measurement standards, measurement errors, units and constants, time and frequency measurement. Modeling papers should bring new modeling techniques to the field and be supported by experimental results. • Materials and their Processing, such as: piezoelectric materials, polymers, metal oxides, III-V and II-VI semiconductors, thick and thin films, optical glass fibres, amorphous, polycrystalline and monocrystalline silicon. • Optoelectronic sensors, such as: photovoltaic diodes, photoconductors, photodiodes, phototransistors, positron-sensitive photodetectors, optoisolators, photodiode arrays, charge-coupled devices, light-emitting diodes, injection lasers and liquid-crystal displays. • Mechanical sensors, such as: metallic, thin-film and semiconductor strain gauges, diffused silicon pressure sensors, silicon accelerometers, solid-state displacement transducers, piezo junction devices, piezoelectric field-effect transducers (PiFETs), tunnel-diode strain sensors, surface acoustic wave devices, silicon micromechanical switches, solid-state flow meters and electronic flow controllers.
