Validation

Tested, judged and backed

Real testing photos, the problems we found, and what outside judges and investors said.

Testing and validation

Tested on real people, problems included

We wired the sensors on a development board, put electrodes on real forearms and watched the trace come through. Then we took it to more than 150 people.

Prototype test in a computer lab: electrodes on a forearm, wired to the board, ECG trace on the monitor — Electrodes on, trace on screen: an early ECG test

150+

people took part in pilot-style testing of the prototype, with input from healthcare professionals along the way.

Do the five sensors give usable readings on real users?
Is one handheld device practical to use?
What breaks outside a controlled room?

What this is not: pilot testing is not a clinical trial. Formal validation and certification are still ahead on the roadmap.

Found in pilots

Thermal drift

Temperature readings slowly drifted away from the true value over a session.

What it means nextBetter calibration and keeping heat from other parts away from the sensor.

Found in pilots

Battery life

Keeping five sensors and a screen running on a small battery, reliably over time, needed more work.

What it means nextPower management in firmware, and sizing the battery against the power-bank form factor.

Found in pilots

Environmental adaptability

Readings that were clean in a controlled room got noisier with changing surroundings and conditions.

What it means nextSignal filtering and isolating the sensors from each other's interference.

Recognition

Judges, then investors, took it seriously

VitalEdge entered Disrupt, the startup programme run by the E-Cell at IIT Guwahati, and kept moving up. Personal names and dates are blurred in the screenshots below.

Step 1Entered Disrupt

IIT Guwahati's startup programme, late 2025.

Step 2ASCEND pitch

Elevator pitch and Q&A in front of mentors.

Step 3Fast-tracked

One of six teams promoted straight to a later pitching round.

Step 4Invited to the finale

Selected for the Disrupt finale, early 2026.
