Microneedles TRIZ Cases
- Needle-shaped body with immiscible aqueous layers for low peeling strength
Immiscible aqueous solutions form distinct projection and support base layers in a needle-shaped body, reducing peeling strength to 8 N/15 mm or lower.
- Segmented Microneedle Design for Intradermal Injection
A segmented microneedle design with a vertical bore and arc-shaped leading edge optimizes fluid flow and mechanical strength.
