一种触觉反馈背心被开发出来，为平衡障碍患者提供感官信息。该系统旨在检测平衡缺陷患者难以察觉的不平衡水平，并提供直观和可感知的感官反馈，允许快速平衡纠正。基于聚二甲基硅氧烷（PDMS）的气动执行器聚集在触觉背心的腹、背、左和右表面，以提供多向的感官反馈。在肩部附近安装了两个双轴加速度计来测量上半身的线加速度和角加速度，并开发了一个系统控制器来调节传感器和执行器之间的通信。对致动器挠度进行表征以优化触觉反馈。在输入压力分别为1.6 psi和4.0 psi时，平均挠度分别为2.6 mm和7.1 mm。在未来的研究中，将进行人类感知测试，以优化该系统的临床应用。
A tactile feedback vest was developed to provide sensory information to patients with balance disorders. The system was designed to detect levels of imbalance that are imperceptible to patients with balance deficit, and to provide intuitive and appreciable sensory feedback that allows for rapid balance correction. Polydimethylsiloxane (PDMS) based pneumatic actuators were clustered on the ventral, dorsal, left and right surfaces of the tactile vest to provide multi-directional sensory feedback. Two biaxial accelerometers were mounted near the shoulder to measure linear and angular acceleration of the upper torso, and a system controller that regulates communication between the sensors and actuators was developed. Actuator deflection was characterized to optimize tactile feedback. Average deflections of 2.6 mm and 7.1 mm were recorded with input pressures of 1.6 psi and 4.0 psi, respectively. In future studies, human perceptual testing will be performed to optimize the system for clinical use.
