随着可穿戴设备的爆发式发展,与其密切联系的可穿戴传感技术也迅速发展。目前研究较多的柔性力学传感器主要为电阻型和电容型,它们不易检测出不同方向的力学变形,不利于复杂多维运动的监测。日前,中科院苏州纳米所陈韦研究团队发展了基于离子压电效应的可穿戴离子型无源力学传感器,并且实现了对于人体多尺度多维活动的实时监测。相关成果发布于《微尺度》。这种离子型传感器以贵金属材料或者石墨烯材料作为电极材料,以离子液体作为电解质。在受到力学形变作用 As wearable devices explode, so-called wearable sensing technologies are also rapidly evolving. At present, most flexible mechanical sensors are mainly resistance type and capacitance type. They are not easy to detect the mechanical deformation in different directions, which is not conducive to the monitoring of complex multidimensional motion. Recently, Chen Wei, a research team at Suzhou Institute of Nanoscience and the Chinese Academy of Sciences, developed a wearable ion passive mechanical sensor based on ion piezoelectric effect and realized real-time monitoring of human multi-scale and multidimensional activities. Relevant results published in the “micro-scale.” This ion sensor with precious metal or graphene material as the electrode material, with ionic liquids as electrolyte.
