Non-invasive transdermal microsystem for drug delivery and diagnostic fluid sampling

Abstract

Textile-integrated microsystem for transdermal drug delivery, characterized in that it has microstructured channels or micropores that enable non-invasive penetration of the upper skin layer.

Description

[0001] The invention relates to a textile-integrated microsystem for the non-invasive transdermal administration of active ingredients, as described in more detail in the claims. The goal is a comfortable, painless, and continuously controllable drug application via the skin – without needles or conventional patch systems. Technical concept: - textile carrier layer with embedded microsystems - microstructured channels or micropores for penetration of the upper skin layer (stratum corneum) - controlled release by means of impulses (e.g. thermal, electrical, magnetic or osmotic) - modular storage and drug reservoirs - integrated sensors for dose control and feedback

[0002] The system is suitable for medical, therapeutic, and cosmetic applications, particularly for people with needle phobia or in mobile settings. It allows precise control of drug release, e.g., via time, temperature, or bioelectrical signals.

Claims

[1] Textile-integrated microsystem for transdermal drug delivery, characterized by that it has microstructured channels or micropores that allow non-invasive penetration of the upper skin layer. [2] Microsystem according to claim 1, characterized by that the active ingredient is released by controllable impulses, triggered, for example, by thermal, electrical, magnetic or osmotic stimulation. [3] Microsystem according to claim 1 or 2, characterized by that the textile carrier layer contains active ingredient reservoirs that can be exchanged or refilled in modules. [4] Microsystem according to one of the preceding claims, characterized by that sensors for dosing control and feedback are integrated with the dispensing control.
