Among various quadruped robots, hydraulically driven quadruped robots show great potential in unstructured environments due to their discrete landing positions and large payloads. As the most critical movement unit of a quadruped robot, the limb leg unit (LLU) directly affects movement speed and reliability, and requires a compact and lightweight design. Inspired by the dexterous skeleton–muscle systems of cheetahs and humans, this paper proposes a highly integrated bionic actuator system for a better dynamic performance of an LLU. We propose that a cylinder barrel with multiple element interfaces and internal smooth channels is realized using metal additive manufacturing, and hybrid lattice structures are introduced into the lightweight design of the piston rod. In addition, additive manufacturing and topology optimization are incorporated to reduce the redundant material of the structural parts of the LLU. The mechanical properties of the actuator system are verified by numerical simulation and experiments, and the power density of the actuators is far greater than that of cheetah muscle. The mass of the optimized LLU is reduced by 24.5%, and the optimized LLU shows better response time performance when given a step signal, and presents a good trajectory tracking ability with the increase in motion frequency.</p><h3 data-test=\"abstract-sub-heading\">Graphic abstract</h3>","PeriodicalId":48627,"journal":{"name":"Bio-Design and Manufacturing","volume":"19 1","pages":""},"PeriodicalIF":7.9,"publicationDate":"2023-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138564009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we created a polyether-ether-ketone (PEEK) joint prosthesis using fused filament fabrication and investigated the effects of printing orientation on its tribological properties using a pin-on-plate tribometer in 25% newborn calf serum. An ultrahigh molecular weight polyethylene transfer film is formed on the surface of PEEK due to the mechanical capture of wear debris by the 3D-printed groove morphology, which is significantly impacted by the printing orientation of PEEK. When the printing orientation was parallel to the sliding direction of friction, the number and size of the transfer film increased due to higher steady stress. This transfer film protected the matrix and reduced the friction coefficient and wear rate of friction pairs by 39.13% and 74.33%, respectively. Furthermore, our findings provide a novel perspective regarding the role of printing orientation in designing knee prostheses, facilitating its practical applications.</p><h3 data-test=\"abstract-sub-heading\">Graphic abstract</h3>","PeriodicalId":48627,"journal":{"name":"Bio-Design and Manufacturing","volume":"1377 1","pages":""},"PeriodicalIF":7.9,"publicationDate":"2023-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138534667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, state-of-the-art microfluidic chips for droplet sorting still suffer from low sorting speeds, sample loss, and labor-intensive preparation procedures. Here, we demonstrate the development of a novel microfluidic chip that integrates droplet generation, on-demand electrostatic droplet charging, and high-throughput sorting. The charging electrode is a copper wire buried above the nozzle of the microchannel, and the deflecting electrode is the phosphate buffered saline in the microchannel, which greatly simplifies the structure and fabrication process of the chip. Moreover, this chip is capable of high-frequency droplet generation and sorting, with a frequency of 11.757 kHz in the drop state. The chip completes the selective charging process via electrostatic induction during droplet generation. On-demand charged microdroplets can arbitrarily move to specific exit channels in a three-dimensional (3D)-deflected electric field, which can be controlled according to user requirements, and the flux of droplet deflection is thereby significantly enhanced. Furthermore, a lossless modification strategy is presented to improve the accuracy of droplet deflection or harvest rate from 97.49% to 99.38% by monitoring the frequency of droplet generation in real time and feeding it back to the charging signal. This chip has great potential for quantitative processing and analysis of single cells for elucidating cell-to-cell variations.</p><h3 data-test=\"abstract-sub-heading\">Graphic abstract</h3>\u0000","PeriodicalId":48627,"journal":{"name":"Bio-Design and Manufacturing","volume":"32 1","pages":""},"PeriodicalIF":7.9,"publicationDate":"2023-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138534680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
