Powering future generations of medical and health care devices mandates the transcutaneous transfer of energy or harvesting energy from the human body fluid. Glucose-driven bio fuel cells (bio-batteries) demonstrate promise as they produce electrical energy from glucose, which is a substrate presents in physiological fluids. Enzymatic biofuel cells can convert chemical energy into electrical energy using enzymes as catalysts. In this study, an air bio-battery was developed for healthcare and medical applications, consisting of a glucose-driven enzymatic biofuel cell using a direct gas-permeable membrane or a gas/liquid porous diaphragm. The power generation characteristics included a maximum current density of 285 μA/cm² and maximum power density of 70.7 μW/cm² in the presence of 5 mmol/L of glucose in solution. In addition, high-performance, long-term-stabilized power generation was achieved using the gas/liquid porous diaphragm for the reactions between oxygen and enzyme. This system can be powered using 5 mmol/L of glucose, the value of which is similar to that of the blood sugar range in humans.

为下一代医疗保健设备提供动力，要求能量经皮传递或从人体液中收集能量。葡萄糖驱动的生物燃料电池（生物电池）因从葡萄糖中产生电能而表现出了希望，葡萄糖是存在于生理液中的一种底物。酶促生物燃料电池可以使用酶作为催化剂将化学能转化为电能。在这项研究中，开发了一种用于医疗保健和医疗应用的空气生物电池，该电池由使用直接透气膜或气/液多孔隔膜的葡萄糖驱动酶促生物燃料电池组成。发电特性包括最大电流密度为285μA/ cm ²和最大功率密度为70.7μW/ cm ²在溶液中存在5 mmol / L葡萄糖的情况下。此外，使用气/液多孔膜进行氧气和酶之间的反应，可以实现高性能，长期稳定的发电。该系统可以使用5 mmol / L的葡萄糖供电，其值与人体血糖范围的值相似。
