Microneedles TRIZ Cases
- Microneedle Cardiac Pacemaker With Self-Harvesting Power
Microneedles harvest energy from myocardial cells, enabling a leadless pacemaker that avoids battery replacement surgeries and lead-related risks.
- Capacitor Stack Charge Harvesting From Millivolt Energy Sources
Sequential capacitor switching captures nano-coulomb charges from millivolt sources, enabling self-powered electronics and implants.
- Hollow Microneedle Molding via Laser Ablation Without Cleanrooms
Laser-ablated cross-over molds form uniform hollow microneedles without cleanrooms, cutting fabrication cost and time for drug delivery.
- Hollow Microneedle Opening Formation Without Burr Distortion
Contactless laser opening after protrusion molding helps hollow microneedles avoid burrs and shape distortion while improving skin delivery stability.
- Microneedle Array Fabrication Using Wire Bonding and Microfluidics
Wire bonding forms solid microneedles with controlled break points and adjacent microfluidic outlets for scalable, low-trauma drug delivery.
- In-Plane Metal Microneedle Arrays for Buckling-Resistant Skin Insertion
Clamped sheet wire cutting enables batch-made high-aspect-ratio metal microneedles with auxiliary insertion support to prevent buckling in skin.
