Method and system for transdermal alcohol monitoring
A method for monitoring intoxication of a user, the method including: receiving a set of samples from a body region of a user; generating an intoxication metric based on the set of samples; and providing a notification to the user based on the intoxication metric. The method can additionally or alternatively include: modifying operation of the transdermal alcohol sensing device based on the intoxication metric; determining contextual data; maintaining a hydration level of the transdermal alcohol sensing device; and any other suitable processes. A system for monitoring intoxication of a user including a sensor and a housing. The system can additionally or alternatively include any or all of: an inlet, a fastener, an electronics subsystem, a user device, and/or any other suitable component.
1. A system for detecting that a user is tampering with a transdermal alcohol sensing device, the system comprising:
the transdermal alcohol sensing device comprising:
a housing comprising a transdermal alcohol sensor;
a wristband coupled to the housing and configured to be coupled to the user in a coupled configuration and in a set of multiple tightness settings, wherein the wristband comprises:
a fastener; and
a tightness detection subsystem, comprising a sensor, configured to detect a parameter associated with the wristband in the coupled configuration, wherein the sensor is incorporated into the fastener;
a processing subsystem, comprising a set of processors, at least partially arranged in the housing, wherein the processing subsystem is configured to:
determine a particular tightness setting of the set of multiple tightness settings based on the parameter; and
in an event that the particular tightness setting does not satisfy a set of criteria, trigger an action, wherein the action comprises transmitting a notification, wherein the notification is transmitted to a second device associated with the user, wherein the second device comprises a mobile user device, and wherein the notification comprises a time in which the user must arrange the wristband in the coupled configuration and to satisfy the set of criteria.
2. The system of claim 1 , wherein the set of criteria comprises a predetermined tightness setting.
3. The system of claim 2 , wherein the predetermined tightness setting is associated with the user.
4. The system of claim 1 , wherein at least a portion of the processing subsystem is arranged onboard the mobile user device.
5. The system of claim 1 , wherein the notification is transmitted to a third device associated with a second user, the second user arranged remotely from the transdermal alcohol sensing device.
6. The system of claim 1 , wherein the housing is configured to receive a set of samples from a skin surface of the user, wherein the processing subsystem is further configured to determine an intoxication metric based on the set of samples.
7. The system of claim 1 , wherein the parameter comprises an electrical resistance.
8. The system of claim 1 , wherein the tightness detection subsystem further comprises a set of flexible printed circuit boards.
9. The system of claim 8 , wherein the set of flexible printed circuit boards is integrated in the wristband.
10. The system of claim 1 , wherein the action comprises a request to the user to record image data of the user and the transdermal alcohol sensing device in a coupled configuration.
11. The system of claim 1 , wherein the transdermal alcohol sensing device further comprises a temperature sensor configured to detect a temperature value, wherein the coupled configuration is detected based at least in part on the temperature value.
12. A method for detecting that a user is tampering with a transdermal alcohol sensing device, the method comprising:
receiving a value of a wristband fastening parameter associated with a wristband of the transdermal alcohol sensing device, determined using a tightness detection subsystem of a fastener of the wristband, wherein the wristband fastening parameter is associated with a tightness setting of a set of multiple tightness settings of the wristband;
comparing the value with a set of criteria; and
in an event that the value of the wristband fastening parameter does not satisfy the set of criteria, triggering an action, wherein the action comprises a request to the user to record image data of the user and the transdermal alcohol sensing device in a coupled configuration.
13. The method of claim 12 , wherein the set of criteria comprises a predetermined wristband tightness.
14. The method of claim 12 , further comprising, at the transdermal alcohol sensing device, receiving a set of transdermal samples from a skin surface of the user.
15. The method of claim 14 , further comprising determining an intoxication metric based on the set of samples.
16. The method of claim 15 , further comprising triggering a second action in response to the intoxication metric exceeding a predetermined threshold, wherein the second action triggers a notification to a second user remote from the transdermal alcohol sensing device.
17. A system for detecting that a user is tampering with a transdermal alcohol sensing device, the system comprising:
the transdermal alcohol sensing device comprising:
a housing comprising a transdermal alcohol sensor;
a wristband coupled to the housing and configured to be coupled to the user in a coupled configuration and in a set of multiple tightness settings, wherein the wristband comprises:
a fastener; and
a tightness detection subsystem, comprising a sensor, configured to detect a parameter associated with the wristband in the coupled configuration, wherein the sensor is incorporated into the fastener;
a processing subsystem, comprising a set of processors, at least partially arranged in the housing, wherein the processing subsystem is configured to:
determine a particular tightness setting of the set of multiple tightness settings based on the parameter; and
in an event that the particular tightness setting does not satisfy a set of criteria, trigger an action, wherein the action comprises a request to the user to record image data of the user and the transdermal alcohol sensing device in a coupled configuration.
