ARPA-H Smart Band-Aid to Measure Chronic Pain in Women

The goal of this clinical trial is to test whether a minimally invasive microneedle patch, called the A-Band (Smart Band-aid), worn on the arm (monitoring key biomarkers in interstitial fluid) and a commercial smartwatch can accurately correlate with self-reported pain in women with chronic pain. A secondary purpose of the study is to identify demographic and clinical variables impacting pain measurement.

The main questions that this study aims to answer are:

* What is the correlation between AI-adjusted pain scores, based on biomarkers and validated tools, and self-reported pain scores? * What influence do demographic and clinical information have in the correlation of these pain scores?

Researchers will compare data from these tools with self-reported pain scores in women with chronic pain and healthy women.

Participants will:

* Be a part of the study for approximately 8 days * Attend 2-3 in-person visits at the applicable clinical center over approximately one week * Wear a Smart Band-Aid (A-Band) at least twice per day for a week, with each application lasting up to 90 minutes * Complete questionnaires regarding medical history, pain information, mental health, sleep, and demographic data * Record daily pain scores * Wear a smartwatch for one week which will collect biophysical data (heart rate, skin response, etc.) * Collect daily saliva samples * Have blood drawn by medical staff at 2 in-person visits
