论文摘要
一个罕见的遗传条件，功能的压电丧失（LOF）的特征是缺乏本体感受和轻触摸，这使功能任务（例如，步行，操纵）变得困难。对于Piezo2-Lof的个体，没有药理治疗或辅助技术。我们提出了一种感官替代设备，该设备通过可检测的触觉刺激传达了本体感受反馈。我们创建了一个可穿戴的原型，该原型将肘部运动的测量值映射到施加到前臂的深压力上。该原型最多适用于18 N，包括一个嵌入式力传感器，可编程以允许各种角度向压力映射。未来的工作包括在健康和压电2个个体中与有或没有设备的本体感受性敏锐度和运动能力进行比较，使用软机器人制作低调的设备，同时为多个关节提供感觉替代，并编码关节动力学的其他方面。
A rare genetic condition, PIEZO2 loss of function (LOF) is characterized by absence of proprioception and light touch, which makes functional tasks (e.g., walking, manipulation) difficult. There are no pharmacological treatments or assistive technologies available for individuals with PIEZO2-LOF. We propose a sensory substitution device that communicates proprioceptive feedback via detectable haptic stimuli. We created a wearable prototype that maps measurements of elbow movement to deep pressure applied to the forearm. The prototype applies up to 18 N, includes an embedded force sensor, and is programmable to allow for various angle-to-pressure mappings. Future work includes comparing proprioceptive acuity and movement ability with and without the device in healthy and PIEZO2-LOF individuals, developing low-profile devices using soft robotics, providing sensory substitution for multiple joints simultaneously, and encoding additional aspects of joint dynamics.
