Recent advances in biosensors, bioelectronics, and system integration allow the development of wristband-type devices for health and performance monitoring of athletes. Although these devices provide adequate sensing outputs, they suffer from signal loss due to improper contact of a rigid sensor with the skin. In addition, when a rubber band tightly secures the sensor to the skin, the gap between sensor and skin causes inevitable motion artifacts, resulting in corrupted data. Consequently, the rigidity and bulky form factor of the existing devices are not suitable for a practical use since athletes typically go through strenuous activities during training and matches. Here, we introduce a soft, wearable flexible hybrid electronics (WFHE) with integrated flexible sensors and circuits in an ultrathin, low-modulus elastomer. The thin-film bioelectronic system avoids the use of bulky, rigid sensors, while providing negligible mechanical and thermal burdens to the wearer. Enabling conformal contact between sensor and skin minimizes undesired motion artifacts. A set of computational and experimental studies of soft materials, flexible mechanics, and system packaging provides key fundamental design factors for a comfortable, reliable, waterproof bioelectronic system. Skin conformal WFHE with sparse signal reconstruction enables reliable, continuous monitoring of photoplethysmogram, heart rate, and activities of athletes. Development of a quantitative analysis between impact force and impact velocity extracted from motion acceleration provides an objective assessment of an athletic punching force. Collectively, this study shows the first demonstration of a wireless, soft, thin-film electronics for a real-time, reliable assessment of athletic health and performance.

皮肤保形，启用软材料的生物电子系统，具有最小化的运动伪影，可对运动员进行可靠的健康和性能监控。

生物传感器，生物电子学和系统集成方面的最新进展允许开发用于运动员健康和性能监测的腕带式设备。尽管这些设备提供了足够的感测输出，但是由于刚性传感器与皮肤的接触不当，它们会遭受信号损失。此外，当橡皮筋将传感器牢固地固定在皮肤上时，传感器与皮肤之间的间隙会导致不可避免的运动伪影，从而导致数据损坏。因此，由于运动员通常在训练和比赛期间进行剧烈的活动，因此现有装置的刚性和体积大的形状不适合实际使用。在这里，我们介绍一种柔软，可穿戴的柔性混合电子器件（WFHE），在超薄，低模量的弹性体中集成了柔性传感器和电路。薄膜生物电子系统避免了使用笨重的刚性传感器，同时为佩戴者提供了可忽略的机械和热负荷。启用传感器和皮肤之间的保形接触可最大程度地减少不良的运动伪影。一组对软材料，柔性力学和系统包装的计算和实验研究为舒适，可靠，防水的生物电子系统提供了关键的基本设计因素。具有稀疏信号重建功能的皮肤保形WFHE可对光体积描记图，心率和运动员的活动进行可靠，连续的监控。冲击力和从运动加速度中提取的冲击速度之间的定量分析的发展提供了对运动型冲床力的客观评估。这项研究共同显示了无线，软，
