Cervical spondylosis is a common disease that is often caused by long-term abnormal cervical curvature due to activities such as reading books and using computers or smartphones. This paper explores building an untethered and skin-integrated device in an e-skin form factor to monitor and haptically correct neck posture. The proposed design features a multilayered structure that integrates all flexible electronic circuits and components into a compact skin space while being untethered and skin conformal. An accelerometer in the e-skin attaches to the neck for posture sensing, while four vibration actuators closely touch the neck skin to provide localized vibrotactile stimuli that encode four-direction correction cues of neck flexion \(\pm \alpha\) and lateral bending \(\pm \beta\). To ensure the reliability of posture sensing and vibrotactile rendering during neck movement, it is necessary to prevent the e-skin device from shifting position. Thus, a hollow structure-based method is implemented for stably attaching the e-skin to the neck skin. Experiments validated the e-skin device’s sensing precision, skin-conformal compliance, stickiness, stability and effectiveness during the motion of neck postures, including its discrimination of localized four-direction vibrotactile cues. A user study verified the device’s performance for sensing and correcting different abnormal neck postures during activities such as using smartphones, reading books, and processing computer files. The proposed e-skin device may create opportunities for more convenient cervical spondylosis prevention and rehabilitation.

颈椎病是一种常见病，往往是由于长期看书、使用电脑、智能手机等活动导致颈椎曲度异常所致。本文探讨了在电子皮肤外形中构建一种不受束缚的皮肤集成设备，以监测和触觉纠正颈部姿势。所提出的设计采用多层结构，将所有柔性电子电路和组件集成到紧凑的皮肤空间中，同时不受束缚且与皮肤保形。电子皮肤中的加速计连接到颈部以进行姿势感测，而四个振动执行器紧密接触颈部皮肤以提供局部振动触觉刺激，编码颈部弯曲 \(\ pm \alpha\)和侧向弯曲的四向校正线索\(\pm \beta\)。为了确保颈部运动过程中姿态传感和振动触觉渲染的可靠性，需要防止电子皮肤设备发生移位。因此，采用基于中空结构的方法将电子皮肤稳定地附着到颈部皮肤。实验验证了电子皮肤设备在颈部姿势运动过程中的传感精度、皮肤适形性、粘性、稳定性和有效性，包括其对局部四向振动触觉线索的辨别能力。一项用户研究验证了该设备在使用智能手机、读书和处理计算机文件等活动期间感知和纠正不同异常颈部姿势的性能。所提出的电子皮肤设备可以为更方便的颈椎病预防和康复创造机会。
