A metal-piezo-metal (M\(\pi \)M) based single-pixel (sensing element or energy harvester) 1 \(\times \) 1 cm energy harvester was fabricated using solution-processed potassium sodium niobate films on aluminum-coated polyethylene terephthalate (PET) substrates. Initial measurements using a full-wave diode bridge rectifier circuit show a real-time response time of (\(\sim \)0.13 s) on the application of variable pressure. The magnitude of the voltage signal generated is \(\sim \) 40 mV greater than the expected rectification drop of \(\sim \) 1.4 V, suggesting significant charge transduction in the harvester.

使用铝上溶液处理的铌酸钾钠薄膜制造了基于金属压电金属 (M \(\pi \) M) 的单像素（传感元件或能量收集器）1 \(\times \) 1 cm 能量收集器涂层的聚对苯二甲酸乙二醇酯 (PET) 基材。使用全波二极管桥式整流器电路的初始测量显示，在应用可变压力时的实时响应时间为 ( \(\sim \) 0.13 s)。产生的电压信号幅度为\(\sim \) 40 mV，比\(\sim \) 1.4 V 的预期整流压降大 40 mV，这表明采集器中有显着的电荷转换。
