摘　　要：针对老年人对外部刺激的触觉感知灵敏度下降的问题,本文设计了一套人体触觉振荡共振传感装置。该系统选用STM32F103ZET6为中央处理器,利用加速度传感器MPU6050采集人体姿态特征信息,通过串口模块CP2012将采集到的信息发送到上位机实时显示和存储,依据姿态信息驱动微电机产生高频振荡作用于触觉感知部位,以提高人体的触觉感知功能。通过对微电机振动产生的振荡进行数字化录音,对其频谱分析观测到不同输入电压下对应电机振动输出频率的变化情况。仿真结果表明,该装置能够产生不同振动强度的高频刺激,为利用振荡共振理论在人体医学功能的应用提供了实验依据。该研究在人体触觉感知领域奠定了实验基础,具有一定的实际应用价值。In order to improve sensorimotor function of older adults with sensory deficits in the perception of cu-taneous and proprioceptive stimuli, this paper designs a set of human tactile transducer device based on the mechanism of vibration resonance. This device uses an embedded platform of STM32F103ZET6 as the main mi-cro-controller. This device processes the attitude features of elderly people＇s activities based on MPU6050 accel-eration transducer. Then, the recorded data are transmitted to the computer through CP2012 for displaying re-al-timely. This device also can convert acceleration values to vibration stimulation of different high frequencies that improve the ability to detect sensory information. By digitally recording the vibrational voice of the micro-motor, the research find that the output vibration frequency of the micro-motor follows different input voltage based on the spectrum analysis. The experimental results show that the designed device can elicit vibrational stimulation rapidly, which provides the potential application of vibrational resonance in human medical engineer-ing. This research is the experimental foundation of human sense perception, and has practical value.
