Environmental hazards often go unnoticed because they are invisible to the naked eye, posing risks to our health over time. Project Calico aims to raise awareness of these risks by augmenting everyday fashion with color-changing chemical sensors that can be observed at a glance or captured by a smartphone camera. Project Calico leverages existing cosmetic and fabrication processes to democratize environmental sensing, enabling creators to make their own accessories. We present two fashionable instantiations of Project Calico involving UV irradiation. EcoHair, created by hair treatment, is UV-sensitive hair that intensifies in color saturation depending on the UV intensity. EcoPatches, created by inkjet printing, can be worn as temporary tattoos that change their color to reflect cumulative UV exposure over time. We present findings from two focus groups regarding the Project Calico vision and gathered insights from their overall impressions and projected use patterns.

印花布项目：用于环境监测的可穿戴化学传感器

环境危害常常被忽视，因为它们是肉眼看不见的，随着时间的推移会对我们的健康构成风险。Calico 项目旨在通过使用可一目了然或被智能手机摄像头捕捉到的变色化学传感器来增强日常时尚，从而提高人们对这些风险的认识。Project Calico 利用现有的化妆品和制造工艺使环境传感大众化，使创作者能够制作自己的配饰。我们展示了两个涉及紫外线照射的 Project Calico 时尚实例。EcoHair 由头发护理制成，是一种对紫外线敏感的头发，其颜色饱和度取决于紫外线强度。通过喷墨打印创建的 EcoPatches 可以作为临时纹身佩戴，随着时间的推移，它们会改变颜色以反映累积的紫外线照射。
