Saliva Drop
A single sample, 20–50 μL, enters the cartridge inlet.
Every layer, documented.
Sample inlet, cartridge slot, and display — the anatomy of a 30–60 second reading.
How to measure your stress.
A single saliva sample, five steps, under a minute — here's what taking a reading actually looks like.
Add your sample
20–50 μL of saliva into the cartridge inlet.
Insert the cartridge
Slide it into the cartridge slot until it clicks.
Press start
One button begins the reading.
Wait 30–60 seconds
The device processes your sample on its own.
View your result
Alpha-amylase concentration and stress level, on-screen and in the app.
AmStress is in prototype validation — figures and timings shown are illustrative, not clinical data.
Built to be used, not just read about.
Fast
A reading in under a minute.
Non-invasive
Just saliva — no needles, no blood draw.
Track over time
See your trend, not just a single number.
At home
No lab visit, no appointment.
Who it's for.
Students

AmStress is currently in prototype validation. Every reading reflects a real-time measurement of salivary alpha-amylase, a biomarker with an established link to physiological stress response. We don't yet have formal clinical validation, and we're upfront about that while we work toward it.
From the lab bench to an instrument.
AmStress grew out of hands-on biosensing research — not a slide deck. Here's the path so far, and what's still ahead.
