Material science, safety, and regulation for tattoo and piercing professionals. Hosted by Patrick Poli, inventor of BioFlex body jewelry. Each episode is a deep dive into the engineering behind body art: biocompatible alloys, implant-grade polymers, REACH and SVHC compliance, needle geometry, and the truth about body jewelry materials.
Patrick Poli hosts Body Art Science by Poli International, a science show with 22 episodes published.
The 400× stiffness gap between 316L stainless steel and flexible body jewellery polymers is not a materials footnote, it is the physical variable that determines whether a fistula heals cleanly or fights its jewellery. T
Cartilage piercings obey different rules than soft-tissue piercings. Avascularity means months of healing through diffusion; placement dictates loading (an industrial is a coupled rigid lever, a daith hides in the ear's
BioFlex PP-R offers specific mechanical advantages for initial piercings, flexibility reduces leverage pressure on the healing channel. But the fastest-healing piercing is one performed and cared for correctly, not one d
PTFE and BioFlex PP-R are both used as non-metal body jewellery, but they are fundamentally different polymers with different processing constraints. PTFE cannot be injection-moulded. It must be extruded as rod. Decorati
Metal piercing jewellery creates a rigid lever at the piercing site. Under impact, a tackle, a fall, a helmet edge, that lever transmits force directly to the tissue. BioFlex PP-R flexes under impact. For rugby nipple pi
Schools, workplaces, and hospitals have policies. Piercings, especially fresh ones, cannot always be removed on demand. The BioFlex Hide-It range was built to bridge that gap: flesh-toned and transparent retainers in fiv
A navel piercing does not need to be removed during pregnancy, but the jewelry must change. Rigid metal bars create mechanical leverage against expanding tissue, causing migration and rejection. BioFlex PP-R bars are tri
Metal oral jewelry, tongue bars, labrets, lip rings, causes measurable enamel erosion and gum recession in a significant proportion of long-term wearers. The mechanism is simple: a material harder than tooth enamel press
Every major MRI safety protocol requires metal jewelry removal before scanning. BioFlex PP-R is non-ferromagnetic, non-conductive, and fully radiolucent, it is invisible to MRI, X-ray, and ultrasound. Patients with unhea
