Summary
Three engineering students from SAS Nagar, Punjab, are developing NeuroTrace, a wearable-free smartphone concept for monitoring stroke survivors at home. Its proposed daily check-in compares voice, facial movement and reaction-time signals with a personal baseline.
Three engineering students from SAS Nagar, Punjab, are developing NeuroTrace, a smartphone-based concept intended to help families monitor stroke survivors at home after hospital discharge. Samsung India says the project is among the Top 20 teams in Samsung Solve for Tomorrow 2026. The proposed system uses a short daily check-in to look for changes from each person’s usual patterns.
How NeuroTrace is designed to work
The planned check-in takes about 45 seconds and uses a phone’s camera and microphone. It is intended to capture three inputs: voice patterns, facial movement and reaction time. During the first 35 days, the system would establish an individual baseline, then look for sustained deviations from it.
This is a personalized change-detection approach: later observations are compared with the same person’s earlier patterns. Samsung says NeuroTrace is designed to issue an alert only when two of the three signals show a deviation at the same time, a rule intended to reduce false alarms. Family caregivers would receive alerts in plain-language Hindi through WhatsApp. The approach is designed to work without a wearable device.
A concept still being developed
The project addresses a practical challenge identified by the team: after patients leave hospital, family members may take on much of their care, while subtle changes can be hard to recognise. The students say their personal experience with stroke in their families motivated the idea.
The team is still working to take NeuroTrace to its next stage. Samsung’s account describes the proposed workflow and alert logic, but reports no patient-study results or measured detection accuracy. The features should therefore be understood as a design under development, rather than an established clinical monitoring service.
The students also say that data security and privacy have become important considerations as they think about the project’s longer-term development. Their participation in the Samsung Solve for Tomorrow bootcamp prompted them to consider users’ needs alongside the technology itself.
