Quantifying hydration-related measures and their association with wearable-derived ergonomic risk in warehouse workers
Agostinelli et al.
The finding, in our words
Warehouse workers frequently presented with concentrated urine pre- and post-shift, and a greater within-shift worsening of urine colour was associated with higher wearable-derived ergonomic risk movement counts. The study demonstrates that self-collected urine samples combined with wearable sensor data can remotely identify hydration-related injury risk in occupational settings.

This review establishes that microsampling across blood, saliva, urine and stool matrices offers validated workflows and regulatory recognition for human biomonitoring comparable to conventional methods. It finds that these decentralised approaches enhance participant acceptability and enable screening in remote or low-resource settings.
This study demonstrates that a memristor sensor can identify distinct electrical signatures in saliva and urine corresponding to different ovulation phases, suggesting a potential route for noninvasive home fertility monitoring.
This narrative review finds that saliva is best suited to repeated neuroendocrine and metabolic measurements during exercise, sweat is most mature for electrolyte and sweat-rate monitoring with wearable compatibility, and exhaled breath offers access to volatile metabolism but remains instrumentally demanding. Each matrix requires matching to a defined clinical or exercise question with matrix-specific validation before translational use.
A smart diaper system that analyses colour changes in urinalysis strips detected urinary tract infection biomarkers correctly in 14 of 15 simulated samples, suggesting potential for automated screening in high-risk groups such as infants and the elderly. The system transmits data via the Internet of Medical Things for remote monitoring, though the authors acknowledge that clinical validation in real patients is still needed.

The authors developed a skin-conformal wearable electrochemical sensor that passively collects sweat and simultaneously measures creatine and lactate in real time, using covalent organic frameworks to stabilise the enzymes. In preliminary human studies with healthy individuals and chronic liver disease patients, the platform tracked dynamic changes in these sweat biomarkers, suggesting a route to non-invasive continuous monitoring of liver metabolic function.
