Sensirion Unveils Quantex 4C: A Wearable IoT Drug Delivery System with Integrated Liquid Flow Sensor

At this year’s MD&M West trade fair in Anaheim, Sensirion and Quantex Arc presented an innovative concept study in infusion technology: the new Quantex 4C wearable drug‑delivery IoT platform.

Sensirion’s LD20 single‑use liquid flow sensor—integral to the concept—offers an exceptionally compact form factor and delivers micro‑ to milliliter‑per‑hour flow measurements with outstanding precision, thanks to its patented CMOSens Technology. The sensor incorporates robust failure‑detection algorithms that flag occlusions, air‑in‑line and other anomalies in real time.

Quantex’s rotary, fixed‑displacement pump underpins the system’s reliability; its design makes it inherently insensitive to variations in line pressure, fluid viscosity and flow rate, ensuring consistent drug delivery.

The Quantex 4C platform marries seamless connectivity with a modular drug‑delivery architecture, enabling continuous therapy monitoring through the integrated single‑use flow sensor. Its compactness, low power draw and cost‑effective components make it feasible to produce a fully wearable device that simultaneously controls and monitors infusion therapy.

The study demonstrates a comprehensive drug‑delivery solution that delivers tangible benefits to patients, clinicians, healthcare providers and pharmaceutical partners. Patients gain a user‑friendly, reliable therapy with minimal training and maintenance, while clinicians and organizations obtain accurate adherence data, streamlined compliance, and heightened confidence in ambulatory treatments.

In next‑generation wearable drug‑delivery devices, reliable failure detection is non‑negotiable. Quantex 4C’s integrated sensor and robust pump architecture provide the transparency and safety required for clinicians and patients to trust the system, making ambulatory therapy a reality.
