AI Technical Summary
Existing microneedle structures are prone to deformation due to insufficient structural strength and have structural limitations, especially when in contact with human skin.
The biodegradable microneedle design employs a two-stage structure, comprising a substrate and multiple biodegradable microneedles. The ratio of the height to the maximum inner diameter of the microneedles is between 1.2 and 2.2. The first stage and the second stage form an angle of 65 degrees to 100 degrees. The tapered shape of the first stage and the frustum or cone shape of the second stage enhance the structural strength.
It improves the structural strength of microneedles, reduces manufacturing difficulty, expands application possibilities, and is suitable for medical and cosmetic fields.
