A totally organic, flexible higher voltage enzymatic biobattery is demonstrated by series connection of carbon fabric-based biobatteries composed of a fructose dehydrogenase-modified anode and a bilirubin oxidase-modified cathode. The fructose/O₂ biobattery was divided and connected so as to maintain the original size (total electrode size: 2 cm²). The series-connected four quarter biobatteries showed increased voltage and current (0.6 V, 30 μA → 1.5 V, 80 μA) for an external load of 20 kΩ, which is a typical skin resistance. The divided batteries were put inside a flexible ion-insulating frame to avoid short-circuit between cells and electrically connected by soft hydrophobic leads that prevented ionic connection by wetting. Because the developed higher voltage biobattery maintains its small size and flexibility, it can even be put on a finger joint and serve to drive a wrist watch.

串联连接的柔性生物电池，用于高压电气皮肤贴片

通过将果糖脱氢酶修饰的阳极和胆红素氧化酶修饰的阴极组成的碳纤维基生物电池的串联连接，可以证明一种完全有机的，柔性的高电压酶生物电池。分开并连接果糖/ O ₂生物电池，以保持原始尺寸（电极总尺寸：2 cm ²）。串联连接的四分之四生物电池在20kΩ的外部负载（典型的皮肤电阻）下显示出更高的电压和电流（0.6 V，30μA→1.5 V，80μA）。将分割后的电池放入柔性离子绝缘框架内，以避免电池之间发生短路，并通过柔软的疏水性引线进行电连接，从而防止通过润湿进行离子连接。由于开发出的高电压生物电池保持了较小的尺寸和灵活性，因此甚至可以将其放在手指关节上并用于驱动手表。
