SPATIAL IMAGING METHODS FOR BIOMEDICAL MONITORING AND SYSTEMS THEREOF
First Claim
1. A method for monitoring at least one biomedical characteristic, comprising:
- illuminating a first microneedle coated with one or more regions of a chemical sensing material;
capturing one or more digital images of the first microneedle, wherein at least one of the one or more digital images is captured after the first coated microneedle has been actuated to penetrate a subject'"'"'s skin;
spatially extracting pixel information from the captured one or more images to define one or more pixel sample areas corresponding to the one or more regions of a chemical sensing material;
determining one or more spectral characteristics for each of the one or more pixel sample areas; and
determining the at least one biomedical characteristic for each of the one or more pixel sample areas based on the determined one or more spectral characteristics for each of the one or more pixel sample areas.

Abstract
A method for monitoring at least one biomedical characteristic is disclosed. A first microneedle coated with one or more regions of a chemical sensing material is illuminated. One or more digital images are captured of the first microneedle, wherein at least one of the one or more digital images is captured after the first coated microneedle has been actuated to penetrate a subject'"'"'s skin. Pixel information is spatially extracted from the captured one or more images to define one or more pixel sample areas corresponding to the one or more regions of a chemical sensing material. One or more spectral characteristics are determined for each of the one or more pixel sample areas. The at least one biomedical characteristic is determined for each of the one or more pixel sample areas based on the determined one or more spectral characteristics for each of the one or more pixel sample areas.

40. A biomedical monitor for determining at least one biomedical characteristic, comprising:
-
at least one microneedle coated with one or more regions of a chemical sensing material; an actuator configured to move the at least one microneedle from a retracted position to an engaged position whereby at least a portion of the at least one microneedle enters a subject'"'"'s skin; at least one light source configured to illuminate the at least one microneedle; an image sensor configured to capture one or more digital images of the at least one microneedle; a computing device coupled to the image sensor and configured to; spatially extract pixel information from the captured one or more images to define one or more pixel sample areas corresponding to the one or more regions of a chemical sensing material; determine one or more spectral characteristics for each of the one or more pixel sample areas; and determine the at least one biomedical characteristic for each of the one or more pixel sample areas based on the determined one or more spectral characteristics for each of the one or more pixel sample areas. - View Dependent Claims (41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55)
