COMPACT MINIMALLY INVASIVE BIOMEDICAL MONITOR
First Claim
1. A biomedical monitor, comprising:
- an array of moveable microneedles coated with a first chemical sensing media;
an actuator configured to move at least one microneedle in the array of microneedles from a retracted position to an engaged position whereby the at least one microneedle enters a subject'"'"'s skin;
an optical system configured to illuminate the at least one microneedle during or after entering the subject'"'"'s skin and monitor the first chemical sensing media from the at least one microneedle, whereby at least one biomedical characteristic is determined based on at least one spectral property of the monitored first chemical sensing media.

Abstract
A biomedical monitor is disclosed. The biomedical monitor has an array of moveable microneedles coated with a first chemical sensing media. The biomedical monitor also has an actuator configured to move at least one microneedle in the array of microneedles from a retracted position to an engaged position whereby the at least one microneedle enters a subject'"'"'s skin. The biomedical monitor further has an optical system configured to illuminate the at least one microneedle during or after entering the subject'"'"'s skin and monitor the first chemical sensing media from the at least one microneedle, whereby at least one biomedical characteristic is determined based on at least one spectral property of the monitored first chemical sensing media. A method of monitoring at least one biomedical characteristic is also disclosed.
