First Claim
Patent Images
1. A wearable sweat sensing device comprising:
- at least one sweat generation unit configured to be placed on a direct stimulation region of a surface of a wearer'"'"'s skin to induce sweating underneath the at least one sweat generation unit, and also to initiate sweating in an indirect stimulation region of skin separated from the direct stimulation region along the skin surface;
at least one sweat collection unit separated from the at least one sweat generation unit by an isolation material, the at least one sweat collection unit capable of collecting one or more sweat samples from the wearer'"'"'s skin, the at least one sweat collection unit being located above the indirect stimulation region when the sweat sensing device is located on the wearer'"'"'s skin to collect sweat sample; and
at least one sensing mechanism in fluid communication with the at least one sweat collection unit for detecting one or more components in the sweat sample.

Abstract
A sweat sensing device includes at least one sweat generation unit capable of initiating sudomotor axon reflex (SAR) sweating in an indirect stimulation region and at least one analysis unit capable of sensing a physiological parameter of sweat, collecting a sweat sample, or a combination thereof. The at least one analysis unit is located above the indirect stimulation region when the sweat sensing device is placed on skin.

24. A wearable sweat sensing device comprising:
-
at least one sweat generation unit configured to induce sweat in a direct stimulation region of a wearer'"'"'s skin underneath the sweat generation unit, and initiating sudomotor axon reflex (SAR) sweating in indirect stimulation regions separated from the direct stimulation regions along the wearer'"'"'s skin; a plurality of sweat collection units configured to be placed spatially within close proximity of the at least one of the sweat generation units to form a honeycomb pattern, the plurality of sweat collection units collecting one or more sweat samples from the wearer'"'"'s skin, each sweat collection unit of the plurality of sweat collection units being located above an indirect stimulation region when the sweat sensing device is placed on the wearer'"'"'s skin; and at least one sensing mechanism in fluid communication with the plurality of sweat collection units for detecting one or more components in the sweat sample.
