The concept of micro-total analysis systems(µTAS)introduced in the early 1990s revolutionized the development of lab-on-a-chip(LoC)technologies by miniaturizing and automating complex laboratory processes.Despite their potential in diagnostics,drug development,and environmental monitoring,the widespread adoption of LoC systems has been hindered by challenges in scalability,integration,and cost-effective mass production.Traditional substrates like silicon,glass,and polymers struggle to meet the multifunctional requirements of practical applications.Lab-on-Printed Circuit Board(Lab-on-PCB)technology has emerged as a transformative solution,leveraging the cost-efficiency,scalability,and precision of PCB fabrication techniques.This platform facilitates the seamless integration of microfluidics,sensors,and actuators within a single device,enabling complex,multifunctional systems suitable for real-world deployment.Recent advancements have demonstrated Lab-on-PCB’s versatility across biomedical applications,such as point-of-care diagnostics,electrochemical biosensing,and molecular detection,as well as drug development and environmental monitoring.This review examines the evolution of Lab-on-PCB technology over the past eight years,focusing on its applications and impact within the research community.By analyzing recent progress in PCB-based microfluidics and biosensing,this work highlights how Lab-on-PCB systems address key technical barriers,paving the way for scalable and practical lab-on-chip solutions.The growing academic and industrial interest in Lab-on-PCB is underscored by a notable increase in publications and patents,signaling its potential for commercialization and broader adoption. 展开更多

The popularization of portable,implantable and wearable microelectronics has greatly stimulated the rapid development of high-power planar micro-supercapacitors(PMSCs).Particularly,the introduction of new functionalities(e.g.,high voltage,flexibility,stretchability,self-healing,electrochromism and photohermal response)to PMSCs is essential for building multifunctional PMSCs and their smart selfpowered integrated microsystems.In this review,we summarized the latest advances in PMSCs from various functional microdevices to their smart integrated microsystems.Primarily,the functionalities of PMSCs are characterized by three major factors to emphasize their electrochemical behavior and unique scope of application.These include but are not limited to high-voltage outputs(realized through asymmetric configuration,novel electrolyte and modular integration),mechanical resilience that includes various feats of flexibility or stretchability,and response to stimuli(self-healing,electrochromic,photo-responsive,or thermal-responsive properties).Furthermore,three representative integrated microsystems including energy harvester-PMSC,PMSC-energy consumption,and all-in-one selfpowered microsystems are elaborately overviewed to understand the emerging intelligent interaction models.Finally,the key perspectives,challenges and opportunities of PMSCs for powering smart microelectronics are proposed in brief. 展开更多

With the rapid development of flexible and portable microelectronics,the extreme demand for miniaturized,mechanically flexible,and integrated microsystems are strongly stimulated.Here,biomass-derived carbons(BDCs)are prepared by KOH activation using Qamgur precursor,exhibiting three-dimensional(3D)hierarchical porous structure.Benefiting from unobstructed 3D hierarchical porous structure,BDCs provide an excellent specific capacitance of 433 F g-1and prominent cyclability without capacitance degradation after 50000 cycles at 50 A g-1.Furthermore,BDC-based planar micro-supercapacitors(MSCs)without metal collector,prepared by mask-assisted coating,exhibit outstanding areal-specific capacitance of 84 mF cm-2and areal energy density of 10.6μWh cm-2,exceeding most of the previous carbon-based MSCs.Impressively,the MSCs disclose extraordinary flexibility with capacitance retention of almost 100%under extreme bending state.More importantly,a flexible planar integrated system composed of the MSC and temperature sensor is assembled to efficiently monitor the temperature variation,providing a feasible route for flexible MSC-based functional micro-devices. 展开更多

Through-silicon via(TSV)technology is widely recognized as one of the most promising interconnect solutions,owing to its ability to dramatically shorten interconnect paths,reduce package di-mensions,decrease power consumption,and enhance device per-formance.Conventional TSVs embedded in low-resistivity silicon interposers are primarily employed in high-performance computing and memory stacking applications.Their application in radio frequency(RF)domains is limited due to severe high-frequency signal losses and TSV-to-TSV crosstalk.Currently,extensive research efforts have been undertaken to address these limitations.This review provides a comprehensive overview of recent advances in the fabrication processes of conventional TSVs,and summarizes the applications and challenges of conventional TSV technique in RF circuits.Furthermore,it overviews the recently developing coaxial TSV designs for RF applications,discussing in detail their fabrication processes,simulation studies,and design optimizations.Finally,it provides an outlook on the future development of TSVs in RF integrated microsystems. 展开更多

Two-dimensional MXenes are key high-capacitance electrode materials for micro-supercapacitors(MSCs)catering to integrated microsystems.However,the narrow electrochemical voltage windows of conventional aqueous electrolytes(≤1.23 V)and symmetric MXene MSCs(typically≤0.6 V)substantially limit their output voltage and energy density.Highly concentrated aqueous electrolytes exhibit lower water molecule activity,which inhibits water splitting and consequently widens the operating voltage window.Herein,we report ultrahigh-voltage aqueous planar asymmetric MSCs(AMSCs)based on a highly concentrated LiCl-gel quasi-solid-state electrolyte with MXene(Ti3C2Tx)as the negative electrode and MnO2 nanosheets as the positive electrode(MXene//MnO2-AMSCs).The MXene//MnO2-AMSCs exhibit a high voltage of up to 2.4 V,attaining an ultrahigh volumetric energy density of 53 mWh cm−3.Furthermore,the in-plane geometry and the quasi-solid-state electrolyte enabled excellent mechanical flexibility and performance uniformity in the serially/parallel connected packs of our AMSCs.Notably,the MXene//MnO2-AMSC-based integrated microsystem,in conjunction with solar cells and consumer electronics,could efficiently realize simultaneous energy harvesting,storage,and conversion.The findings of this study provide insights for constructing high-voltage aqueous MXene-based AMSCs as safe and self-sufficient micropower sources in smart integrated microsystems. 展开更多

The escalating demand for microano-sized devices,such as microano-robots,intelligent portable/wearable microsystems,and implantable medical microdevices,necessitates the expeditious development of integrated microsystems incorporating energy conversion,storage,and consumption.Critical bottlenecks in microscale energy storage/sensors and their integrated systems are being addressed by exploring new technologies and new materials,e.g.,MXene,holding great potential for developing lightweight and deformable integrated microdevices.This review summarizes the latest progress and milestones in the realization of MXene-based micro-supercapacitors(MSCs)and sensor arrays,and thus discusses the design fundamentals and key advancements of MXene-based energy conversion-storageconsumption integrated microsystems.Finally,we outline the key challenges in fabricating MXenebased MSCs/sensors and their self-powered integrated microsystems,which is crucial for their practical applications.Particularly,we illuminate viable solutions to such unsolved issues and highlight the exciting opportunities. 展开更多
