Self-powered sensors are analytical devices able to generate their own energy, either from the sample itself or from their surroundings. The conventional approaches rely heavily on silicon-based electronics, which results in increased complexity and cost, and prevents the broader use of these smart systems. Here we show that electrochromic materials can overcome the existing limitations by simplifying device construction and avoiding the need for silicon-based electronics entirely. Electrochromic displays can be built into compact self-powered electrochemical sensors that give quantitative information readable by the naked eye, simply controlling the current path inside them through a combination of specially arranged materials. The concept is validated by a glucose biosensor coupled horizontally to a Prussian blue display designed as a distance-meter proportional to (glucose) concentration. This approach represents a breakthrough for self-powered sensors, and extends the application of electrochromic materials beyond smart windows and displays, into sensing and quantification.
自供电传感器是能够从样本本身或周围环境中产生自身能量的分析设备。传统方法严重依赖基于硅的电子器件，这导致复杂性和成本增加，并阻碍了这些智能系统的更广泛应用。在此我们表明，电致变色材料可以通过简化设备结构并完全避免使用基于硅的电子器件来克服现有局限性。电致变色显示器可以内置到紧凑的自供电电化学传感器中，这些传感器通过特殊排列的材料组合简单地控制其内部的电流路径，从而提供肉眼可读的定量信息。通过将葡萄糖生物传感器水平耦合到设计为与（葡萄糖）浓度成比例的测距仪的普鲁士蓝显示器，验证了这一概念。这种方法代表了自供电传感器的一项突破，并将电致变色材料的应用从智能窗户和显示器扩展到传感和定量领域。
