Reader
Handheld point-of-care engine with integrated display and sensing control.
Product
Hardware built for the frontline.
A compact sensing system under development — reader, contact pad, wearable concept, and clinic kit — designed for antenatal and decentralised care.
System
One sensing stack. Clear pairing.
ZAWADI is intended as a non-invasive screening device that applies controlled light, captures the optical-acoustic response, and presents a research-prototype readout.
Lineup
Reader, pad, wearable, kit.
Contact pad
Skin interface for stable placement — no lancet, no blood tube, no biohazard stream.
Wristband
Wearable concept for longitudinal monitoring alongside clinic measurements.
Clinic kit
Reader, pads, and field pairing assembled for antenatal and community deploy.
Workflow
Place. Pulse. Analyse. Display.
A four-step path designed for point-of-care simplicity — still under validation.
01
Place
Seat the sensing head on an approved measurement site. The earlobe is included in current design exploration.
02
Pulse
Selected wavelengths illuminate tissue; the device captures the optical-acoustic response.
03
Analyse
Signal features are processed with automatic quality checks before a result is offered.
04
Display
Integrated screen presents a research-prototype readout or prompts a repeat measurement.
Design principles
What the product must achieve.
Measurement quality
Stable acquisition and automatic quality checks.
Usability
Simple positioning, minimal steps, clear feedback.
Portability
Compact form factor for point-of-care use.
Equity
Performance evaluation across relevant skin tones and patient groups.
Serviceability
Practical cleaning, power, maintenance, and replacement.
Responsible output
Screening information linked to an appropriate confirmatory pathway.
