基于摩擦电驱动液晶的波浪传感系统

By using a wave sensing system based on triboelectrically driven liquid crystal, the mechanical energy transmission module and triboelectric nanogenerator are used to convert wave motion into electrical signals, which are then converted into light signals by a smart reflector. This solves the problem that existing wave monitors cannot obtain a complete wave profile and enables self-powered, cable-free wave monitoring.

Abstract

本申请公开了一种基于摩擦电驱动液晶的波浪传感系统，包括激光发射单元、自供电传感单元和探测单元，对于自供电感应单元，采用机械能传动模块将海浪上下运动的能量转化为摩擦纳米发电机的旋转能量。采用两个啮合方向相反的单向超越离合器以控制两个电压输出参数不同的摩擦纳米发电机，以对海浪的上升阶段和下降阶段予以区分，通过基于聚合物网络液晶的智能反射器将摩擦纳米发电机的电信号转化为光信号，从而以自供能的方式实现机械‑电‑光信号的转换。本申请的自供电传感单元受岸上激光发射器发射的激光照射，探测单元可远程检测反射激光来探测海浪运动，不需能量供应，无需电缆连接，可大大延长连续观测海洋的时间跨度，以获取整个海浪谱图。
