单纤维计算机实现纺织网络和分布式推理

摘要

尽管可穿戴技术取得了进步1,2, 在实现持续位于人体上的分布式计算方面仍然存在障碍。本文展示了一种纺织纤维计算机，它以小于 5 克的质量，单片集成了模拟传感、数字存储、处理和通信功能。借助可折叠的中间层，微设备的二维焊盘架构被映射到符合纤维几何形状的三维圆柱布局。通过与螺旋铜微线的连接，八个微设备被热拉制成具有超过 60% 弹性的可机洗纤维。这种可编程纤维，包含一个 32 位浮点微控制器，即使在编织、梭织、针织或缝纫到服装中时，也能独立执行边缘计算任务。组装过程的通用性允许通过简单的修改来集成其他功能，包括一个可充电的纤维电源，可以为计算机供电近 6 小时。最后，我们通过实现两种无线通信方案，克服了刚性互连的长期限制，这两种方案包括编织光链路和缝纫插入的射频通信。为了证明它的实用性，我们展示了配备四个纤维计算机（每个肢体一个）的服装，这些纤维计算机运行独立训练的神经网络，在对身体活动进行分类时平均达到 67% 的准确率。然而，当联网时，使用简单的加权投票，推理准确率提高到 95%。
