中国科学院北京纳米能源与系统研究所的研究人员研制出一种灵敏的、基于摩擦纳米发电机的肢体运动传感器。其纳米柱状阵列可大幅提高器件的监测灵敏度,通过监测人在睡眠中的肢体运动引起器件内摩擦层的相对运动产生的电压输出信号,可以实时收集和记录人在睡眠中的运动时间和次数,睡眠中的翻身运动等肢体运动都可通过收集器件的电信号进行监测。
Researchers at the Beijing Institute of Nanoenergy and Systems, Chinese Academy of Sciences, have developed a sensitive, limb-based motion sensor based on a friction nano-generator. The nano-columnar array can greatly improve the monitoring sensitivity of the device. The voltage output signal generated by monitoring the relative movement of the friction layer in the device caused by limb movement during sleep can collect and record the movement time and frequency of the human during sleep in real time, Body movements such as turning over during sleep can be monitored by collecting electrical signals from the device.
