Hand orthosis designed and produced in DIY biocomposites from agrowaste

Abstract A hand orthosis has been designed and produced in Do-It-Yourself (DIY) biocomposites from agrowaste to serve to relieve the symptoms of technology-related orthopaedic issues, most particularly BlackBerry thumb. The two orthoses were produced using a self-developed material, and were intended as prototypes for a larger and customized offer, being adaptable to specific needs and preventing skin irritation. The base material is formed by a starch–sorbitol–vinegar bioplastic with a local refuse from food production (protective liquid for buffalo mozzarella) layered around an internal structure of active components, including the use of agrowaste (hemp fibres or hibiscus leaves), therefore obtaining a higher sustainability. The application of aromas (ginger, lemon or chamomile) to obtain benefits overtime for the users was also explored. The higher adaptability of the self-produced material was effective in impeding movements that are possibly delaying rehabilitation. Two prototypes were produced: one of which included beyond the base material, hemp fibres and hibiscus leaves and ginger, whereas the other included hemp fibres, chamomile and lemon skins. Both prototypes showed potential properties and were also durable to aging: one of them proved more mechanically adapted for use, showing a substantial isotropy of properties in its whole structure. The results demonstrate that hand orthoses can be produced in a customized way and in a variety of textures and internal structures, which would promote a wider acceptance among public.
