Early detection and treatment of cardiovascular diseases (CVDs) can be significantly enhanced through the use of flexible wearable electrocardiogram (ECG) sensors, potentially reducing CVD-related mortality. This paper introduces an ECG-on-Chip (EoC) solution tailored for flexible ECG sensors, incorporating novel features to address common challenges in wearable ECG technology. The EoC integrates a chopper-stabilized capacitively-coupled instrumentation amplifier (CS-CCIA),ensuring a high common-mode rejection ratio (CMRR) and low noise performance. Performance is further boosted via a positive feedback loop (PFL) and a programmable gain amplifier (PGA) with shared on-chip calibration logic, which enhances input impedance and minimizes gain variability to ensure consistent algorithm performance. Additionally, a secondary chopping technique is employed to further reduce noise, achieving an input-referred noise level of 454 nVrms. The embedded algorithm within the EoC is designed to extract clinically meaningful features, facilitating robust real-time arrhythmia analysis. Fabricated using a 0.18μm CMOS process, the EoC consumes 14.9μW with a supply voltage of 1.2 V. The algorithm’s efficacy has been validated over 0.4 million heartbeats, demonstrating a sensitivity of over 99.7%for R-peak detection and 98.3%for arrhythmia analysis. To demonstrate practical application, the EoC has been integrated with a commercial Bluetooth low energy (BLE)transceiver, forming a wireless arrhythmia monitoring sensor equipped with dry electrodes. This system consumes 292.04μW in arrhythmia-aware transmission mode, supporting 13 days of operation with a 30 mAh thin-film battery.

探讨不同阻隔性的聚乳酸共衣康酸丁二醇酯/纳米二氧化硅共聚物薄膜[poly(L-lactic-co-butanediol itaconate)nano-silica copolymer films,PLBI-SiO_(2)]包装对发酵酸奶贮藏效果,并对贮藏期间酸奶的理化指标和活菌数进行测定。结果表明:在4℃贮藏0~21 d期间,所有包装组的pH都呈现下降趋势,PLBI-SiO_(2)0.5%包装组与对照(市售)组在贮藏后期pH下降得到减缓;在贮藏期间,PLBI-SiO_(2)0.5%包装组与对照(市售)组能有效维持酸奶的质构特性与持水能力,同时也保持良好的感官评价与表观黏度;所有包装组的活菌数在整个贮藏期间都呈现逐渐降低的趋势,但随包装阻隔性的提高,下降幅度得到减缓,PLBI-SiO_(2)0.5%包装组与对照组在贮藏21 d时,保加利亚乳杆菌与嗜热链球菌都保持在10~7 CFU/mL以上。综合各项指标,PLBI-SiO_(2)0.5%包装组在贮藏21 d可以维持酸奶贮藏品质并几近于市售包装组,这为酸奶及其他发酵乳替代包装材料提供了一定的理论基础。

The applications of single-cell and spatial technologies in recent times have revolutionized the present understanding of cellular states and the cellular heterogeneity inherent in complex biological systems. These advancements offer unprecedented resolution in the examination of the functional genomics of individual cells and their spatial context within tissues. In this review, we have comprehensively discussed the historical development and recent progress in the field of single-cell and spatial genomics. We have reviewed the breakthroughs in single-cell multi-omics technologies, spatial genomics methods, and the computational strategies employed toward the analyses of singlecell atlas data. Furthermore, we have highlighted the advances made in constructing cellular atlases and their clinical applications,particularly in the context of disease. Finally, we have discussed the emerging trends, challenges, and opportunities in this rapidly evolving field.
