Microneedles TRIZ Cases
- Microneedle Sheet Flat-Raised Transition for Safe Handling
Bending the sheet body transitions microneedles from a flat storage state to a raised application position, preventing accidental contact during handling.
- Hybrid Micromachining and Electroplating for Microstructure Array Mold Fabrication
A hybrid method forms microstructure array molds using electroplated metal base layers to replicate complex geometries.
- Microneedle Patch Base Composition for Demolding and Adhesion
HPMC and PVP/VA composites prevent brittleness during drying, ensuring structural integrity and skin adhesion.
- Nanoprojection Array Fabrication via Porous Silicon Release
Selective etching of a sacrificial porous silicon layer allows damage-free transfer of nanoprojection arrays to flexible substrates.
- Nozzle With Concave-Convex End For Water-Soluble Sheet Applicator
A nozzle with a concave-convex end portion holds sheet-like water-soluble preparations for reliable skin application.
- Smart Adapter for Infusion Devices Drug Verification
A smart adapter embeds sensors to detect drug concentration and flow rate in infusion systems.
- Biocompatible Polymer Microneedles for Transdermal Drug Delivery
Photolithography creates crosslinked biopolymer microneedles that bypass the stratum corneum barrier to deliver large hydrophilic molecules without degradation.
- Segmented Microneedle Array for Controlled Drug Delivery and Pain Reduction
A segmented microneedle array combines hollow drug delivery protrusions with solid blood flow promoters to optimize transdermal absorption.
- Microneedle Patch Insulin Delivery with Glucose Sensor
A microneedle patch delivers insulin through hollow needles while a sensor measures sweat glucose levels for automated control.
- Multi-needle module adhesive injection and assembly
Front plate adhesive injection bonds cap part and housing simultaneously, eliminating complex rear-side filling defects.
- Phase-Transition Microneedle Patches for Transdermal Protein Delivery
Freeze-thaw treatment creates physical cross-links in polymeric microneedles, delivering large molecular weight therapeutics without protein denaturation.
- Microneedle Patch With Viscosity-Reducing Adhesion Layer
A microneedle patch uses an adhesion layer with a viscosity-reducing substance to control active substance release from the needle tip.
- Microneedle Patch Mold Alignment via Polymeric Female Die
Polymeric female die mediates metal mold alignment, correcting microneedle position deviations to boost production yield.
