Blood pressure monitoring via wearables

I usually don’t cover anything related to “benign disorders”, but implants are getting mainstream. I came across a press-release and sharing a link to the original paper.

Continuous cuffless monitoring of arterial blood pressure via graphene bioimpedance tattoos | Nature Nanotechnology

Continuous monitoring of arterial blood pressure (BP) in non-clinical (ambulatory) settings is essential for understanding numerous health conditions, including cardiovascular diseases. Besides their importance in medical diagnosis, ambulatory BP monitoring platforms can advance disease correlation with individual behaviour, daily habits and lifestyle, potentially enabling analysis of root causes, prognosis and disease prevention. Although conventional ambulatory BP devices exist, they are uncomfortable, bulky and intrusive. Here we introduce a wearable continuous BP monitoring platform that is based on electrical bioimpedance and leverages atomically thin, self-adhesive, lightweight and unobtrusive graphene electronic tattoos as human bioelectronic interfaces. The graphene electronic tattoos are used to monitor arterial BP for >300 min, a period tenfold longer than reported in previous studies. The BP is recorded continuously and non-invasively, with an accuracy of 0.2 ± 4.5 mm Hg for diastolic pressures and 0.2 ± 5.8 mm Hg for systolic pressures, a performance equivalent to Grade A classification.

This is how it looks like.

I believe IoT (and ambulatory monitoring) is slowly becoming mainstream. If this deluge of data is monitored and integrated via EMR, it will give consistent data and “guideline” in the historical lows, allowing cardiologists (or other specialists) to gain insight into proper management.
