Title: Strain-controlled Graphene-Polymer Angular Actuator
ABSTRACT We demonstrate a suspended graphene-(poly(methyl methacrylate) (PMMA) polymer angular displacement actuator enabled by variable elastic modulus of the perforated stacked structure. Azimuthal flexures support a central disc-shaped membrane, and compression of the membrane can be used to control the rotation of the entire structure. Irradiating the PMMA on graphene stack with 5 kV electrons in a convention scanning electron microscope reduces the elastic modulus of the PMMA and allows graphene’s built in strain to dominate and compress the flexures, thus rotating the actuator.  more » « less

    Abstract Integration of conductive electrodes with 3D tissue models can have great potential for applications in bioelectronics, drug screening, and implantable devices. As conventional electrodes cannot be easily integrated on 3D, polymeric, and biocompatible substrates, alternatives are highly desirable. Graphene offers significant advantages over conventional electrodes due to its mechanical flexibility and robustness, biocompatibility, and electrical properties. However, the transfer of chemical vapor deposition graphene onto millimeter scale 3D structures is challenging using conventional wet graphene transfer methods with a rigid poly (methyl methacrylate) (PMMA) supportive layer. Here, a biocompatible 3D graphene transfer method onto 3D printed structure using a soft poly ethylene glycol diacrylate (PEGDA) supportive layer to integrate the graphene layer with a 3D engineered ring of skeletal muscle tissue is reported. The use of softer PEGDA supportive layer, with a 105times lower Young's modulus compared to PMMA, results in conformal integration of the graphene with 3D printed pillars and allows electrical stimulation and actuation of the muscle ring with various applied voltages and frequencies. The graphene integration method can be applied to many 3D tissue models and be used as a platform for electrical interfaces to 3D biological tissue system.

    Adhesives require molecular contact, which is governed by roughness, modulus, and load. Here, we measured adhesion for stiff glassy polymer layers of varying thickness on top of a soft elastomer with rough substrates. We found that a 90-nm-thick PMMA layer on a softer elastic block was sufficient to drop macroscopic adhesion to almost zero during the loading cycle. This drop in adhesion for bilayers follows the modified Persson-Tosatti model, where the elastic energy for conformal contact depends on the thickness and modulus of the bilayer. In contrast, we observed no dependence on thickness of the PMMA layer on the work of adhesion calculated using the pull-off forces. Understanding how mechanical gradients (like bilayers) affect adhesion is critical for areas such as adhesion, friction, and colloidal and granular physics.

    Leveraging living muscle as an efficient and adaptive actuator for soft robots has been of increasing interest over the past decade, with a focus on proof‐of‐concept demonstrations of function. Reproducible design and scalable manufacturing of biohybrid machines requires methods to increase the stroke output of strain‐limited muscle actuators and enable accurate and precise quality control and performance monitoring. Compliant mechanical elements, termed flexures, are designed to enhance muscle contractile stroke to ≈5× previously reported values and decode contraction dynamics with high spatiotemporal resolution. Combining rigid and flexible elements within a linear elastic flexure enables us to outperform the sensitivity of gold standard elastomeric beam‐based measurements of muscle contraction at both low‐ and high‐frequency stimulations. Flexures are leveraged to make quantitative comparisons of force, work, and power outputs in muscle actuators, driving us to discover a new observation of frequency‐dependent fatigue in muscle, and also develop a novel method for tuning muscle contractile dynamics in a frequency‐independent manner. By enhancing the contractile stroke of muscle actuators and precisely tuning contractile dynamics and endurance with unprecedented precision, this study sets the stage for leveraging flexures to improve robust, reproducible, and predictive design and manufacturing of next‐generation biohybrid robots.

    High quality graphene can efficiently be grown on large surface areas of copper foil through chemical vapor deposition (CVD). To transfer CVD graphene onto a substrate for use in nanoscale photonic devices a process called electrochemical bubble delamination is utilized. During the delamination and transfer procedure the CVD graphene is at its most susceptible. Therefore, the incentive to develop a minimal-contact and replicable process is high. The use of a mechanical stage controlled by an actuator is a promising method of avoiding significant mechanical defects like folding or tearing and is capable of ensuring the film is delaminated at the right speed and from bottom to top. The quality of the transferred graphene is varied with regions of high-quality graphene up to 80x80µm while the typical transfer region has a large presence of gaps, cracks, and PMMA residues. It is evident that extending the mechanical assistance to other parts of the transfer process may be valuable, however, the occurrence of mechanical and chemical defects in the transferred graphene is still a limiting factor in the use of electrochemical bubble delamination.

    This work is focused on the mass transport of methanol and the methanol-assisted crack healing in poly(methyl methacrylate) (PMMA)–graphene composites at different temperatures. The effect of the fraction of graphene on the mass transport of methanol and the methanol-assisted crack healing is also studied. The experimental results reveal that adding graphene to the PMMA matrix increases the resistance to the migration/diffusion of methanol and polymer chains in the PMMA matrix, and the absorption of methanol follows anomalous diffusion. The activation energies for the case I transport and case II transport in the PMMA–graphene composites are relatively independent of the fraction of graphene, and are larger than the corresponding ones in pure PMMA. Increasing the healing time and healing temperature allows for more polymer chains to migrate/diffuse across fractured surfaces, leading to the increase in the fracture strength of the crack-healed PMMA–graphene composites.
