The flexible and portable paper-based sensors have a broad potential application in electronic detection and devices. In this work, a flexible thermoresponsive paper sensor was reported by writing on A4 paper with composite pencil leads which contain thermoresponsive pyrene-based ionic liquid [Pyrmim][Br]. The [Pyrmim][Br] was transferred onto the A4 paper surface with graphite by pencil writing for the facile preparation of thermal-sensitive paper chips. The as-prepared paper sensor was very sensitive to the NIR irradiation and warm objects. What is more, the pliable paper chip also had regular responses along with the varication of the folding angles, which could be employed for the angle goniometer of electronic robots.
柔性便携的纸质传感器在电子检测和设备方面有广泛的潜在应用。在这项工作中，通过用含有热敏性芘基离子液体 [Pyrmim][Br]的复合铅笔在 A4 纸上写字，报道了一种柔性热敏纸传感器。通过铅笔在 A4 纸上写字，将 [Pyrmim][Br]与石墨一起转移到 A4 纸表面，以方便制备热敏纸芯片。所制备的纸传感器对近红外辐射和温暖物体非常敏感。更重要的是，柔软的纸芯片还可以随着折叠角度的变化而产生规则的响应，可用于电子机器人的角度测量计。
