This is a prospective observational clinical trial in which 20 participants with a history of dependence on prescription or non-prescription opioids will be recruited for collection of physiologic data via wearable sensors during a 14-day inpatient detoxification treatment. The EmbracePlus Smartwatch and Corti Sensor will be worn continuously throughout the 14-day treatment course to detect heart rate, heart rate variability, skin conductance, skin temperature, motion, and cortisol levels.

DEVICE

EmbracePlus Smartwatch

The EmbracePlus is worn on the user's wrist and continuously collects raw data via specific sensors. These data can be wirelessly transmitted to a paired mobile device. The data received are analyzed by EmpaDSP, which computes the user physiological parameters. The Care App is responsible for transmitting raw data, device information, Care App-specific information, and computed physiological parameters to the Empatica Cloud. The device supports continuous data collection for monitoring of the following physiological parameters: * Peripheral skin temperature * Electrodermal activity * Blood Oxygen Saturation under no motion conditions * Activity associated with movement during sleep. The EmbracePlus Watch has been used in previous human subject research studies for bio-physiological data collection in other medical conditions and have confirmed that there is minimal risk to participants. This device is therefore exempt from any IDE requirements.

DEVICE

Corti Sensor

The Corti Wearable is a sweat sensor that is worn continuously measure cortisol, melatonin, tumor necrosis alpha interleukin-6 (IL-6) in the protein analytes in the sweat of participants via electrochemical impedance spectroscopy. The Corti Wearable comprises a plastic reader and a replaceable polymer sweat-sensing strip with zinc oxide (ZnO) coated electrodes that is worn on the participant's forearm. It is manufactured through a screen-printing technique that allows for an affinity-based interaction between a capture probe antibody and the target molecule generating electrochemical activity. The Cort Wearable has been used in previous human subject research studies for bio-physiological data collection in other medical conditions and have confirmed that there is minimal risk to participants. This device is therefore exempt from any IDE requirements.

Participant is between 18 and 50 years of age 4. Participant is English proficient 5. Participant is able to provide informed consent and function at an intellectual level sufficient for study requirements 6. Participant is willing to wear wearable sensors for 14 days

Exclusion criteria

1. Participant presents current evidence of an uncontrolled and/or clinically significant medical condition or psychiatric condition 2. Participant has a history of epileptic seizures 3. Participant has a history of neurological diseases or traumatic brain injury 4. Participant has recent suicide attempt leading to current hospital admission or continued expressed suicidal ideation 5. Subject has significant current suicidal ideation within 30 days prior to Screening as evidenced by answering "yes" to questions 4 or 5 on the suicidal ideation portion of the Columbia-Suicide Severity Rating Scale (C-SSRS) completed at Screening, that, in the opinion of the investigator, warrants exclusion from the trial 6.
