| 제목 | Fabrication of Skin Attachable Temperature Sensor Using Metal Thin-Film with Serpentine Patterning |
| 초록 | Human body temperature and thermometry of skin are the critical information that provides important aspects of human health and physiology. Therefore, continuous and accurate body temperature measurement is required for the observation of physical abnormalities. However, conventional thermometers are rigid and flat, making it difficult for users to use them when real-time detection of body temperature is required for a long time. Also, non-contact thermometers such as IR cameras limit the space range of user movement while continuous measurement. In this work, we fabricated a flexible, stretchable temperature sensor that can be laminated onto the skin directly so that continuous and real-time measurements are possible. Rigid metal components were deposited using an electron beam evaporator in a thin-film type so the device can be flexible. We used and compared various metal thin films and graphene-based materials to find out the best properties as temperature sensors. Here we identified the characteristics by measuring the resistance values with a digital multimeter. Furthermore, photolithographic techniques were utilized to pattern the sensor in a wavy serpentine shape. This pattern allows the device to be stretchable so it can integrate with soft and curvilinear skin surfaces. Also, since we used polymer materials as the substrate, it can minimize irritation to users even it is attached for a long time. These thin, patterned, and soft properties of our device can therefore reduce delamination so that precise and continuous detection of temperature can be performed. |
