Development of a urinometer for automatic measurement of urine flow in catheterized patients
Lafuente et al.
The finding, in our words
A non-invasive wearable urinometer using an infrared barrier and LoRaWAN measures urine flow from less than 1 to 500 ml/h with errors below 15% compared with an infusion pump gold standard, and detects urine colour; this supports remote, continuous monitoring of diuresis and haematuria in catheterized patients.
A paraphrase to the Library’s standard, never the abstract. The source is one link away and is always the authority.
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.
The review finds that lab-on-chip liquid biopsy technologies are sufficiently mature for distanced cancer screening and follow-up, enabling patient-centric sample collection that reduces exposure risks during pandemics.

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.
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.

Salivary cortisol is suitable as an adjunctive measure in decentralised monitoring, with lateral-flow assays providing rapid low-cost discrete measurements and wearable platforms enabling higher-frequency collection but facing biofouling and calibration challenges. Suitability requires validation in authentic saliva against reference methods, not merely low detection limits.
