Kind: research · Impact: low

## In brief

- A research article listed in the nature.com medical research feed examines sensor-skin contact pressure in wearable photoplethysmography.
- The title describes contact pressure as a hidden confounder in wearable photoplethysmography biosensing.
- The source provides no summary, so the study's methods and quantitative findings are not available.

## Why it matters

If sensor-skin contact pressure confounds photoplethysmography signals, readings from wearable devices may be affected by factors other than the physiological quantity being measured.
