This Letter proposed a new hardware approach based on the design of an intelligent system to manage energy storage sources in order to improve the battery life span. It is dedicated for the biomedical low power devices and specially an implantable biosensor since it consumes only 1.5mW. It involves three types of digital circuits based on the CMOS transistor which are: voltage comparator, analogue switches and OOK MICS transmitter. The proposed circuit manages the system supply and especially the supercapacitor charging. It enables the supercapacitor to supply the biosensor for 15 hours per 24 hours which presents 62% of the initial supply system life span. This would therefore prolong the battery life span, avoid the risk of the thermal leakage which is dangerous for the human body, and solve the problems of deep discharge and the decay of the discharge voltage for the supercapacitor.

这封信提出了一种基于智能系统设计的新硬件方法来管理能量存储源，以提高电池寿命。它专用于生物医学低功率设备，特别是植入式生物传感器，因为它仅消耗 1.5mW。它涉及三种基于CMOS晶体管的数字电路：电压比较器、模拟开关和OOK MICS发射器。建议的电路管理系统电源，尤其是超级电容器充电。它使超级电容器能够每 24 小时为生物传感器供电 15 小时，占初始供电系统寿命的 62%。因此，这将延长电池寿命，避免对人体造成危险的热泄漏风险，
