Sensing solutions for life-critical medical devices
From infusion pumps and dialysis machines to ventilators and surgical tools — SMD sensors are embedded in medical equipment used by millions of patients worldwide. Every sensor is engineered to ISO 13485 standards.
Product Families
Sensor families trusted by medical OEMs
Ranked by relevance to medical device applications based on design-in frequency across IV, dialysis, ventilator, and surgical platforms.
Ultrasonic Flow Sensors
PrimaryNon-contact clamp-on flow sensing for IV pumps and infusion systems. No fluid contact — eliminates contamination risk and simplifies sterilisation.
Bubble Detection Sensors
PrimaryPatient-safety-critical air bubble detection in IV lines, extracorporeal circuits, and cardiac bypass. Sub-millisecond response, non-invasive clamp-on.
Load Cell Sensors
PrimaryMiniaturised load cells for surgical tools, haptic feedback, and gravimetric drug delivery systems. Autoclavable designs available.
Pressure Sensors
Thin film pressure sensors for dialysis, ventilators, and patient monitoring. Biocompatible materials, long-term stability, and full traceability.
Temperature Sensors
Precise temperature measurement for patient monitoring, drug storage, and lab equipment where ±0.1°C accuracy is non-negotiable.
Why SMD for Medical
When patient safety depends on measurement accuracy
Medical device OEMs require more than just a sensor supplier — they need a quality-certified partner who understands regulatory requirements, design validation, and long-term supply stability. SMD Sensors has operated as a trusted medical OEM component supplier for over 30 years.
Our ISO 13485 quality management system ensures every medical-grade sensor is designed, manufactured, and documented to meet FDA, EU MDR, and IEC standards. We provide full traceability, lot documentation, and change notification protocols as standard.

Applications
Medical devices we power
Infusion & IV Pumps
Ultra-precise flow sensing for drug delivery systems where dosing accuracy is life-critical. Our ultrasonic flow sensors detect flow rates as low as 0.1 mL/min with no fluid contact.
Dialysis Equipment
Continuous, reliable monitoring of dialysate flow and pressure throughout multi-hour treatment sessions. Sensors rated for sterilization cycles and aggressive cleaning agents.
Ventilators & Respiratory
Fast-response differential pressure sensors for breath detection and tidal volume measurement. Millisecond response times to track rapid breathing cycles accurately.
Surgical & Lab Equipment
Miniaturized load cells and pressure sensors for surgical tools, lab balances, centrifuges, and fluid handling systems where precision and repeatability are non-negotiable.
Patient Monitoring
Non-invasive pressure and temperature sensors embedded into wearable and bedside monitoring devices, providing continuous vital sign data streams to clinical systems.
Bubble & Air Detection
Clamp-on ultrasonic bubble detectors protecting patients from air embolism in IV lines, extracorporeal circuits, and cardiac bypass systems.
