Periodic Reporting for period 1 - Stripe-o-Morph (Morphing tubular structures for adaptive biomedical devices)
Reporting period: 2022-10-01 to 2024-03-31
The goal of the project is to develop morphing tubular structures with superior morphing capabilities, delivering higher shape fidelity and better precision in the control of the forces transmitted in the morphing process and during the normal functioning of the structure or device.
The new morphing concept revisits some classical results of differential geometry, reinterpreted as a morphing algorithm: by lateral modulations of the stretches of a surface, one can program a flat sheet to acquire a desired curved shape (Gaussian morphing). Some unicellular organisms (euglenids), whose outer envelope is made of interlocked pellicle strips that can slide one relative to the adjacent one, can execute remarkable shape changes thanks to the stretches arising from the sliding of the pellicle strips.
This concept of morphing-by-sliding, suitably engineered and now protected by a patent that has been granted in November 2023, is the key to obtain unprecedented morphing capabilities in sheets and tubular structures. Applications to medical devices, industrial design, civil engineering, and architecture are being considered.
1. improvements on the material and manufacturing process, leading to a new, optimized 3d-printing protocol
2. identification of application areas for the morphing-by-sliding concept, in the areas of biomedical devices, civil engineering, and architecture
3. discovery of a new mathematical model for the morphing process, leading to the development of a computer interactive design tool
The physical demonstrators will be used to highlight the morphing performance of large scale prototypes to showcase them to innovators, businesses and investors, to facilitate access to markets and finance.
The software demonstrators will be used to allow innovators to experiment with the potential of the morphing-by-sliding technology and identify possible uses of the technology to respond to unmet demands in market segments that have not been explored yet.
