Abstract
Described are methods and devices (100) for measuring a sweat property of skin (12) in response to at least one test material or component (172, 174, 176, 178). Embodiments of the device include a plurality of different sweat stimulation sites. The Sweat stimulation sites may include one or more sweat stimulant reservoirs (142, 144, 146, 148) configured to deliver a sweat stimulant to the surface of the skin (12). Embodiments may also include at least one electrode (150, 152, 154, 156, 158) for measuring a sweat property or to iontophoretically deliver the sweat stimulant from the reservoir (142, 144, 146, 148). In embodiments, the sweat stimulant is selected from acetylcholine, carbachol, methacholine, bethanechol, muscarine, pilocarpine, oxotremorine, and combinations thereof.
Claims25
A device for measuring a sweat property comprising one or more sweat stimulant reservoirs configured to deliver a sweat stimulant to the surface of the skin, at least one electrode for measuring a sweat property, and at least one test material or component;
- wherein the at least one test material or component is impregnated into a secondary material.
A device for measuring a sweat property comprising one or more sweat stimulant reservoirs configured to deliver a sweat stimulant to the surface of the skin, at least one electrode for measuring a sweat property, and at least one test material or component;
- wherein the at least one test material or component is stored in a microfluidic pump configured to deliver the test material or component to the surface of the skin.
A device for measuring a sweat property comprising one or more sweat stimulant reservoirs configured to deliver a sweat stimulant to the surface of the skin, at least one electrode for measuring a sweat property, and at least one test material or component;
- wherein the at least one test material or component is positioned between the skin and the sweat stimulant reservoir.
