Gas sensor-embedded smartphones would offer the opportunity of on-site tracking of gas molecules for various applications, for example, harmful air pollutant alarms or noninvasive assessment of health status. Nevertheless, high power consumption and difficulty in replacing malfunctioned sensors as well as limited space in the smartphone to host the sensor restrain the relevant advancements. In this article, we create a smartphone case-based sensing platform by integrating the functional units into a smartphone case, which performs a low detection limit of 117 ppb to acetone and high specificity. Particularly, dimming glass-regulated light fidelity (Li-Fi) communication is successfully developed, allowing the sensing platform to operate with relatively low power consumption (around 217 mW). Experimental proof on harmful gas sensing and potential clinic application is implemented with the sensing platform, demonstrating satisfactory sensing performance and acceptable health risk pre-warning accuracy (87%). Thus, the developed smartphone case-based sensing platform would be a good candidate for realizing harmful gas alarms and noninvasive assessment of health status.

用于现场丙酮跟踪的基于智能手机外壳的气体传感平台
嵌入气体传感器的智能手机将为各种应用提供现场跟踪气体分子的机会，例如有害空气污染物警报或健康状况的无创评估。然而，高功耗和更换故障传感器的难度以及智能手机中容纳传感器的空间有限限制了相关的进步。在本文中，我们通过将功能单元集成到智能手机外壳中来创建基于智能手机外壳的传感平台，该平台对丙酮的检测限低至 117 ppb，且特异性高。特别是调光玻璃调节光保真（Li-Fi）通信的成功开发，使传感平台能够以相对较低的功耗（约217 mW）运行。通过传感平台实现了有害气体传感和潜在临床应用的实验证明，展示了令人满意的传感性能和可接受的健康风险预警准确度（87%）。因此，开发的基于智能手机案例的传感平台将是实现有害气体警报和健康状况无创评估的良好候选者。
