Hydrogen peroxide (HO) is a key molecule in numerous physiological, industrial, and environmental processes. HO is monitored using various methods like colorimetry, luminescence, fluorescence, and electrochemical methods. Here, we aim to provide a comprehensive review of solid state sensors to monitor HO. The review covers three categories of sensors: chemiresistive, conductometric, and field effect transistors. A brief description of the sensing mechanisms of these sensors has been provided. All three sensor types are evaluated based on the sensing parameters like sensitivity, limit of detection, measuring range and response time. We highlight those sensors which have advanced the field by using innovative materials or sensor fabrication techniques. Finally, we discuss the limitations of current solid state sensors and the future directions for research and development in this exciting area.
过氧化氢（HO）是许多生理、工业和环境过程中的关键分子。HO 的监测方法有很多，如比色法、发光法、荧光法和电化学方法。在这里，我们旨在提供一个全面的综述，以了解用于监测 HO 的固态传感器。该综述涵盖了三类传感器：电阻式、电导式和场效应晶体管。简要描述了这些传感器的传感机制。根据灵敏度、检测限、测量范围和响应时间等传感参数，对所有三种传感器类型进行了评估。我们强调了那些通过使用创新材料或传感器制造技术来推动该领域发展的传感器。最后，我们讨论了当前固态传感器的局限性以及在这个令人兴奋的领域的未来研究和发展方向。
