Keynote Lecture 1: Construction and Emergent Functionality of Cellular Buildup Wet Robotics

Keisuke Morishimakeisuke2
Osaka University, Japan

Abstract: While previous works on cell-based devices for integrated chemical systems have focused on exploiting biochemical functions of cells, we demonstrated the direct utilization of on-board cells as microactuators converting chemical energy into mechanical energy and an environmentally robust hybrid (biotic–abiotic) robotic system that uses living components, called “Cellular Build Up Wet Nano Robotics”. This novel muscle-powered bioactuator successfully show autonomous beating at room temperature for a long time without maintenance. Experimental results suggest the possibility of constructing an environmentally robust hybrid wet robotic system with living components and open up a new science and technology, biorobotic approach, medical, environmental monitoring, agriculture and industrial application. To build up such a soft and wet machines will lead us an innovative fundamental change and produce a new principle and design to future man-made systems.

Keynote Lecture 4: Carbon-based Biomimetic Materials and Functional Manufacturing

Hongzhong Liuhongzhong2
Xi’an Jiaotong University, China

Abstract: Have you seen the soft robotic that can exploiting the interaction with the environment, as observed in the animal model, and can elongate, shorten, bend, and stiffen? Will the robotic that can pass through obstacles in the Terminator come true? All of these peculiar phenomena can be realized using smart materials. Smart materials are the materials at the function of perception and actuation, which possess the ability to change their physical properties (shape, volume, stiffness, viscosity, damping, etc.) in a specific manner in response to external stimulus, such as electric, magnetic, temperature, stress, moisture, pH, etc. With the developments of materials science, smart materials are playing an important role in accomplishing new style of sensing and actuating manners in soft robotics, biomimetic fabrications, drug delivery, tissue engineering and other biomedical applications. However, it is urgent and challengeable in remote control, flexibility and biocompatibility in the research of new smart materials.
Graphene, due to its excellent thermal conductivity, high flexibility, brilliant photothermal conversion efficiency under nIR and good compatibility, is becoming a rising star in the development of carbon nanocomposites based smart composites. Inspired by a bilayer phenomenon that two sheet-like components with different mechanical properties coupled together will attains a shape to facilitate an equilibrium between its constituent elements, a soft smart material is constituted by a bilayer structure, which is composed of pure polydimethylsiloxane (PDMS) layer and a PDMS/GNPs composites layer. The bilayer materials can be driven to bend to the PDMS/GNPs side by light irradiation, as shown in Figure 1a.The excellent reversibility and repeatability in actuation are revealed by sweeping and multicycle light irradiation. It shows that the presented bilayer smart material in various shapes, i.e., fish-like shapes, can float and swim to perspective location in fluid (i.e., water), whose moving directions and velocities can be remotely adjusted by light, indicating an excellent light-actuation ability and well controllability, as shown in Figure 1b. The results may be not only hopeful in developing light-driven drug-delivery platform, but also the bio-robotic microgrippers applying in-vivo and in-vitro.

Keynote Lecture 6: Nanotube Fountain Pens: Towards 3D Printing of Metallic Nanostructures

Lixin Donglixin2
Michigan State University, USA

Abstract: The introduction of additive manufacturing (aka 3D printing) by Chuck Hull of 3D Systems Corp. in the industry marked the advantage of building from bottom up and distributed manufacturing. Printing with metals is treated as the final frontier in 3D printing and has achieved remarkable advancement in recent years. Compared with conventional metal component manufacturing process that usually lasts from weeks to months and lacks dynamics in product design, 3D printers allow the lean manufacturing of the machine parts, indicating a new revolution in the manufacturing industry. The recent progress in the miniaturization of the electromechanical system raises the question that whether the 3D metal printing can be realized at the nanoscale or even atomic level, which is also the core of bottom-up nanomanufacturing. A nanotube fountain pen (NFP) is developed for this purpose. The NFP uses a metal-filled carbon nanotube as a pen-tip injector for “writing” and a reservoir for continuous mass feeding. The deposition of the metal is based on nanofluidic mass flow from the pen-tip nanotube driven by electromigration and the continuous mass feeding is implemented by inter-nanotube mass transport of the encapsulated metals. Nanostructures and devices have been prototyped using this technique including a sphere-on-pillar optical antenna and an elastic and shape-adaptive tip for sliding probe methods. With the potential to serve as a pin for directly writing 3D metallic nanostructures, the NFP will be the key towards the development of a 3D printing system for large scale nanomanufacturing of metallic structures.

Keynote Lecture 7: A New Transduction Scheme of Physical Quantity Detection Based on the Mode Localization of Weakly Coupled Resonators

Honglong Changhonglong2
Northwestern Polytechnical University, China

Abstract: MEMS resonators have been researched over several decades. The applications of the resonators have covered the fields from communications, inertial sensors, atomic force microscopy, chemical sensors to medical diagnostics etc. A classical detection method for MEMS sensors is to measure the resonance frequency change caused by the physical quantity. Over the past ten years, a new transduction scheme based on the mode localization of weakly coupled resonators (WCRs) was proposed. The mode localization phenomenon could be described as that in a nearly symmetric WCRs system, the presence of a small symmetry-breaking perturbation on the structure will lead to a vibration energy confinement. Different from the traditional resonant sensors, eigenstates or amplitude ratio rather not the resonance frequency are chosen as the output metrics for such sensors. Using the mode localization, the sensitivity of WCRs based sensors could be enhanced by orders of magnitude compared to traditional resonant sensors.
This talk will review some milestones on this new transduction scheme, and present the first experimental application of the transduction scheme to inertial sensors such as accelerometers and gyroscopes.
