A wearable for managing hypertension, silently.
A medical wearable and connected mobile ecosystem for passive blood pressure monitoring - designed for the 1 in 3 Americans living with hypertension.
01 - The Problem
1 in 3 Americans have hypertension. Most of them don't know it.
Hypertension is a silent chronic condition - symptoms don't appear until severe. Without continuous monitoring, neither patients nor physicians can understand patterns or prevent crises.
02 - The Opportunity
How might we enable passive monitoring without adding friction?
Managing chronic hypertension demands constant vigilance - daily measurements, medication adherence, and coordination with a care network. Today's tools make all of this harder than it needs to be.
03 - The Solution
A wearable + mobile ecosystem.
// 01
Continuous passive monitoring
Plexus monitors blood pressure around the clock using optical and oscillometric sensing - no button presses, no interruptions.
// 02
Connected care network
The companion app links patient, family, and physician in one shared view — enabling real-time awareness and proactive intervention.
// 03
Automated diagnosis
Pattern recognition across time surfaces clinically meaningful insights - identifying trends before they become emergencies.
Physical Design
Plexus Device
Designed to disappear into daily life. Worn on the wrist, the device features an LED channel that gives ambient feedback on blood pressure stages, battery levels, and device status - without demanding attention.
The Device
04 - User Research
Three personas. One chronic condition.
Qualitative research with patients, caregivers, and physicians surfaced distinct user archetypes - each with a different relationship to their illness, their care network, and technology.

05 - Key Insights
Three critical gaps in hypertension management.
Research with patients and physicians revealed consistent barriers - spanning monitoring, communication, and behavior change.
// 01
Monitoring
Blood pressure changes rapidly and needs 24/7 tracking for physicians to understand patterns - current tools require manual effort and create gaps.
// 02
Care Network
Added life events - stress, pandemic, isolation - demand faster, easier communication between patient and care network that today's tools can't provide.
// 03
Lifestyle
Chronic illness demands sustained behavior change, not just medication. Tools to meaningfully support healthy habits and close the loop with physicians are largely absent.
06 - Design Explorations
From system map to product ecosystem.
Multiple design directions explored - from data dashboards to physical device form factors - stress-tested against patient needs, caregiver workflows, and clinical requirements.
07 - Ecosystem
Plexus Ecosystem.
A closed feedback loop - device monitors, app surfaces insights, care network stays informed, physician acts proactively. Chronic care without chronic friction.
08 - Information Architecture
Mapping the patient journey from monitoring to care.
09 - Userflow
From daily measurement to physician alert.
10 - Final Screens
Designed for everyday life.
11 - Learnings
What this project taught us.
Learnings
- Mapping the full ecosystem before designing any interface ensured every feature had a clear purpose in the care journey.
- Hypertension management is a family and community challenge. The care network is a first-class user group, not a secondary consideration.
- Automating data collection removes the single biggest barrier to consistent monitoring - daily manual effort.
- Chronic illness doesn't happen in a vacuum. Stress, pandemic, isolation - the design had to account for life events, not just clinical states.
