This study presents a biomimetic approach for developing scalable 3D printable models of a California sea lion pelvis using DICOM images derived from CT and MRI scans. The images were processed using Simpleware ScanIP software to create accurate and detailed representations of the targeted anatomy. The resulting models were then modified and optimized for 3D printing. The motivation behind this research is to provide a realistic and cost-effective alternative to traditional training methods for veterinary blood collection. The proposed work has the potential to enhance veterinary education and training, improving the quality of care provided to animal patients
Varifocal lenses are a lens with different focal lengths and, therefore, magnification. These are used extensively in the optics industry as progressive lenses in eyewear. A focal length gradient exists along the lens height, so objects magnify as the user looks downwards. Unfortunately, progressive lenses are rigid materials making them closer to quasi-varifocal lenses. In this present study, varifocal lenses can change focal length to a constant value. This study investigates polyvinyl chloride (PVC) gel and Electrohydraulic Actuators Powered by Induced Interfacial Charges (EPIC) actuators as varifocal lenses. Polyvinyl chloride (PVC) gels are a new type of dielectric elastomer actuator only investigated at the start of the century. The transparent gels are known for producing displacement under an effective voltage in a mechanism known as anodophilic creep, the axisymmetric tendency to deform towards the anode surface. The EPIC actuator is a novel application of PVC gels that places
Biomimicry is the art of robotics mimicking systems in nature and could potentially include evolutionarily optimized skin and nervous systems of living organisms. This potential artificial skin application for soft polymeric gel sensors may be used in damaged skin replacement, prosthetics, or other soft robotic applications. Characterization of polyvinyl chloride (PVC) sensing in static planar orientations has been performed in prior studies. However, further testing is required to understand this mechanoelectrical transduction and its dependence on surface orientation and loading condition. PVC gel sensing capabilities under varying surface morphologies and loading conditions are unknown. This characterization is critical because it will determine practical operating conditions and applications for PVC gel sensors. The goal of this study is to analyze the electrical response of PVC gels in planar and curved surface orientations at static and dynamic loading conditions with novel elect
