“…The results obtained from the BACtrack® Skyn transdermal alcohol monitoring device show promise for its use (46). The relationship between TAC/BrAC was highly correlated, especially in the post-45-minute time period after drink-ing.…”

A discrete wrist-worn transdermal alcohol monitoring device, the BACtrack® Skyn™, was evaluated in a subject over three drinking sessions. The relationship between transdermal alcohol concentration (TAC) and breath alcohol concentration (BrAC) was evaluated. The relationship amongst contemporaneous TAC/BrAC measurements revealed an R of 0.65, while the relationship in the 45-minute post-drinking phase revealed an R of 0.89. Results obtained show promise for its use. Further research is needed with many subjects in real-world drinking situations.

“…A study involving 30 participants wearing both SCRAM and Skyn in the laboratory indicated strong correlations between Skyn and BAC and also substantially reduced lag times with Skyn versus SCRAM [31]. A field study ( n = 10) indicated that Skyn detected alcohol soon after drinking onset (~30 minutes), and a 2‐week feasibility study ( n = 12) indicated acceptability of Skyn for longer‐term wear [51]. Of particular relevance, in a study that represents the largest objective transdermal sensor validation study conducted to date ( n = 73), we applied time–series feature extraction paired with tree‐based machine‐learning algorithms to Skyn data collected in the laboratory [9].…”

“…Regarding the transdermal monitors themselves, although suitable for many research functions, additional work is needed before these devices are ready for widespread application. To date, the majority of new-generation sensor validation work has involved BACtrack Skyn [9,31,37,51]. Earlier Skyn prototypes showed high rates of device failure, although reliability has improved substantially with newer prototypes [9,31].…”

The use of transdermal alcohol monitors has burgeoned in recent years, now encompassing hundreds of thousands of individuals globally. A new generation of sensors promises to expand the range of applications for transdermal technology exponentially, and advances in machine‐learning modeling approaches offer new methods for translating the data produced by transdermal devices. This article provides (1) a review of transdermal sensor research conducted to date, including an analysis of methodological features of past studies potentially key in driving reported sensor performance; (2) updates on methodological developments likely to be transformative for the field of transdermal sensing, including the development of new‐generation sensors featuring smartphone integration and rapid sampling capabilities as well as developments in machine‐learning analytics suited to data produced by these novel sensors and; (3) an analysis of the expanded range of applications for this new generation of sensor, together with corresponding requirements for sensor accuracy and temporal specificity. We also note questions as yet unanswered and key directions for future research.

“…Skyn bracelet 30) found strong correlations between breath alcohol concentration (BrAC) and Skyn TAC readings [11]. Two studies (N=10, N=12) testing the Skyn in the field found evidence for initial acceptability and detection of self-reported drinking [12]. In a final larger study (N = 73) testing the Skyn in the laboratory and comparing readings to repeated BrAC readings, a strong correlation (r=.907) was observed between BrAC and estimated blood alcohol concentration (eBAC) readings derived from TAC using machine learning models [13].…”

Transdermal alcohol monitoring allows for continuous, non-invasive, objective, and remote measurement of alcohol consumption. We evaluated feasibility and acceptability of participant use of the BACtrack Skyn biosensor bracelet in daily life. Heavy drinkers (n=20) wore the Skyn and self-reported drinking behavior for 7 days, followed by an individual interview. Recruitment and retention benchmarks were met, supporting feasibility. Participants provided both positive and constructive feedback on the Skyn during interviews, and usability of the bracelet was deemed "good". Most missing data were inconsequential (<5 mins), with data available 85% of the time participants were asked to wear it. Missing data was largely expected and due to bracelet removal during bathing or charging. Overall, results indicate promise in our ability to integrate this tool into research and/or clinical practice, passively and objectively monitoring alcohol use in participants and/or patients with minimal burden.
