通过集成内置的柔性葡萄糖/O2生物膜，研制出一种可灵活附着在皮肤上，并在S 30岁时加水激活的电动皮肤贴片。后者由葡萄糖脱氢酶(GDH)修饰的阳极和铁(II)酞菁(FePc)修饰的阴极组成。使用含有葡萄糖和缓冲电解质的柔性吸水海绵，通过在贴片内部深处添加水来实现贴片成分的快速活化。通过优化海绵槽中葡萄糖和电解液的含量，维持了约10μA的贴片电流12h以上。整个贴片柔软且高度柔韧，以适应弯曲的皮肤表面，这是因为它很薄(1；2毫米)，而且所有贴片组件都很灵活，包括基于碳纤维织物的酶电极。
An electrical skin patch that can be flexibly attached to the skin and activated in 30 s by adding water was developed by integrating a built-in flexible glucose/O2 biobattery. The latter consisted of a glucose dehydrogenase (GDH)-modified anode and an iron(II) phthalocyanine (FePc)-modified cathode. The quick activation of the patch components by water addition deep inside the patch was achieved by using a flexible water-absorbing sponge containing glucose and buffer electrolyte. A patch current of about 10 μA was maintained for more than 12 h by optimizing the amount of glucose and electrolyte contained in the sponge tank. The entire patch was soft and highly flexible to conform to curved skin surfaces, owing to its thinness (<2 mm) and the flexibility of all the patch components, including the enzyme electrodes based on the carbon fabric.
