讲座简介：
用于非侵入式个人健康监测的实用可穿戴电子平台需要先进的传感模式和高度集成的电子系统。然而，由于能量供应不足、传感系统能力有限、用户体验问题、复杂的电路调节以及设备尺寸较大，这些系统在长期连续健康监测方面面临诸多限制。通过应用可穿戴微电网设计理念，我们提出了一种可穿戴、无线、能量自主的多路汗液检测系统，该系统可在指尖上运行。该系统利用高效、自我电压调节的可穿戴微电网，由酶生物燃料电池（BFCs）和氯化银-锌（AgCl-Zn）电池组成，从自然出汗中获取并储存能量，无需任何身体运动或体力消耗。关键的设计考量包括精准的能量预算、兼容的电路调节以及针对特定场景的互补特性，这些都被用于无缝创建能量微电网，并将其与传感器阵列和微控制器集成至单个指尖。该传感模式结合了渗透泵和纸基流体系统，能够持续将指尖自然汗液输送到传感器阵列，以实现按需的多代谢物检测。通过低功耗电子设备进行信号采集和无线数据传输，该系统可以完全依靠自然指尖汗液供电，持续检测葡萄糖、抗坏血酸、乳酸和左旋多巴水平。这种集成在指尖的汗液监测系统为轻松、可靠、且自我可持续的综合非侵入式代谢监测提供了一种解决方案。

Lecture Bio:
Practical wearable electronics platforms for non-invasive personal health monitoring require advanced sensing modalities and highly integrated electronic systems. However, these systems face limitations in long-term continuous healthcare monitoring due to inadequate energy supply, limited sensing system capabilities, user experience issues, complex circuitry regulation, and large device dimensions. By applying the wearable microgrid design concept, we present a wearable, wireless, energy-autonomous, multiplexed sweat sensing system that operates on the fingertip. This system utilizes a high-efficiency, self-voltage-regulated wearable microgrid, composed of enzymatic biofuel cells (BFCs) and silver chloride-zinc (AgCl-Zn) batteries, to harvest and store energy from natural perspiration without requiring any body movement or physical exertion. Critical design considerations, including accurate energy budgeting, compatible circuit regulation, and scenario-specific complementary characteristics, were employed to seamlessly create the energy microgrid and integrate it with the sensor array and microcontroller onto a single fingertip. The sensing modality combines an osmotic pump and paper fluidic system to continuously deliver natural fingertip perspiration to a sensor array for on-demand multi-metabolite sensing. Coupled with low-power electronics for signal acquisition and wireless data transmission, the system can be solely powered by natural fingertip perspiration while detecting glucose, ascorbate, lactate, and levodopa levels over extended periods. The integrated sweat monitoring system on the fingertip provides a solution for effortless, reliable, and self-sustainable comprehensive non-invasive metabolic monitoring.
