Embedded 3D printing of Soft Materials: Embedded Shapeability and Applications to Human Cochlear Modelling

【Abstract】

Embedded 3D printing has emerged as a promising tool for on-demand fabrication of non-self-supporting soft materials. This technology, which involves architecting soft materials in supportive baths, has held great potential for applications ranging from tissue engineering to soft robotics applications. Our research lab focuses on soft material fabrication and printing. In this presentation, we will explore the recent advances in embedded 3D printing technology, and discuss two of our recent research works. The first study investigated the ‘embedded shapeability’ of different categories of hydrogel inks and proposed a general guideline for supportive bath selection in embedded printing. Building on these findings, we then utilised the embedded printing technique to develop biomimetic electroanatomical cochlear models. Our 3D printed cochlear models are able to provide clinical informatics for cochlear implant patients, such as the current spread problems.

嵌入式3D打印是一種制造復雜結構的柔性材料的先進手段。這種技術通過在支撐浴中打印，可構建具有三維結構的柔性材料，在組織工程及軟體機器人等眾多領域上具有具大潛在的應用。我們研究團隊專注于軟性材料的制造和打印技術。在本次報告中, 我將討論嵌入式3D打印技術的最新進展, 并討論我們的兩項研究工作。我們通過研究不同類型的水凝膠墨水在各種典型支撐浴的"可打印及成形性", 提出了一種通用和簡化的支撐浴選擇指南。此方法可以拓寬水凝膠的成形性，從而實現多種功能。在此基礎上,我們進一步利用嵌入式打印技術開發了仿生耳蝸模型。該耳蝸模型能模擬真實活體耳蝸的特性，可預測電子耳蝸在使用過程的"電流擴散"特性。

Compliant Mechanism: Macro & Micro Applications

【ABSTRACT】

Compliant mechanism is a type of mechanism that achieves force transmission and motion transmission through its elastic deformation, whose inspiration comes from natural animals. Compliant mechanisms have been widely applied in both our daily life and industrial applications. The compliant mechanism has merits in terms of no backlash, frictionless, and low assembly requirements. Therefore, compared with the rigid linkage mechanism, the compliant mechanism has a huge advantage in high-precision industries, especially in the fields of micro/nano manipulation, biomimetic robots, and intelligent structures. Based on the compliant mechanism, our team has successfully developed many novel devices to solve the requirements and challenges of different application environments and tasks. In this report, I will introduce two development devices based on compliant mechanism, which are dedicated to macro and micro tasks, respectively. For the macro polishing task, we developed a passive polishing end-effector with adjustable constant force and wide operating angle, which improves the adaptivity of the passive polishing end-effector to various polishing tasks. For the wireless micromanipulation in the closed environment, we developed a magnetically actuated biaxial robot with a compact structure and easy operation, which can grip, in-plane rotate, and locomote samples in a closed environment.

柔性機構是一種通過彈性體變形來實現力和運動傳遞的機構，其產生靈感來源于自然生物體，在日常生活和工業實踐中得到了廣泛的應用。柔性機構由于其無傳動間隙、無摩擦、裝配要求低等特點，相對于剛性連接機構，其在高精尖領域中展現出顯著的優勢，特別是微納操作、仿生機構、智能結構等領域。基于柔性機構，我們成功研發出多種新型的裝備，以解決不同應用場景與不同任務中的需求以及挑戰。本次報告將介紹我們針對宏觀與微觀中幾種不同應用場景所研制的基于柔性機構的精密機器人解決方案。面對宏觀中的拋光打磨任務，我們研發了一種被動式恒力拋光打磨末端執行器，其恒力大小可靈活調整并允許在多個角度對器件進行打磨，擴寬了現有被動式恒力打磨的應用范圍。面對微觀中封閉場景中無線操作的任務需求，我們研制了一種磁驅動雙軸微操作機器人，可以在封閉環境中對物體進行夾取、平面旋轉以及移動等操作。

Interconnect and assembly in soft bioelectronics

【ABSTRACT】

Stretchable electronic devices that can retain the function of the circuits and electronic components under mechanical deformation largely extend the concept of electronics into new application scenarios. Using such stretchable devices as intelligent human-machine interface, bi-directional interaction between biological world and digital world can be effectively established. To assemble a mechanically compliant stretchable device, highly stable interconnects between its modules are required for systematic robustness. The interconnects in stretchable devices need to tolerate stress concentration that may limit their stretching and ultimately cause debonding failure. This talk will focus on the development of an innovative connection interface that enable robust stretchable devices to be reliably assembled in a Lego-like manner, via a unique bi-phasic nanostructure. Using such connection interface, complex stretchable devices such as implantable neuro-electrodes and on-skin electrophysiological devices can be easily assembled with high robustness.

柔性生物電子器件具有與人體組織相匹配的力學性能，在體表智能傳感、體內生理監測、深度人機交互、軟體機器感應等領域至關重要。完整的柔性電子系統通常由可拉伸模塊、硅基剛性模塊、封裝模塊等材料、形狀因子不同的模塊組成。因此，柔性電子系統的研發不僅需要提高可拉伸模塊本身的性能，還需要確保模塊之間連接的可靠性。在此次報告中，我將介紹我們關于柔性電子模塊連接在納米合成、材料機理和工程應用上的新進展，即通過基于雙連續納米互穿網絡的可拉伸通用接口，對于可拉伸模塊、剛性模塊以及封裝模塊，進行高效穩定的“樂高式”組裝。采用該新型接口的柔性醫療器件可高精度、高保真、抗干擾地監測體內外不同器官，包括表皮、腦皮層、坐骨神經、腓骨肌肉、膀胱等，相比采用商用導電膠組裝的系統，信號質量大幅提升，有望簡化和加速柔性電子器件的研發過程。總的來說，我們正致力于從基礎理論出發，面向實際工程應用來研發新一代柔性生物電子器件。
