Cadi Scientific ThermoSensor: Hospital Case Study & Impact

Cadi Scientific is a Singapore-based healthcare tech company founded in 2003. It specializes in active RFID-based devices for hospitals—leveraging wireless sensing and tracking to simplify workflows and improve patient care. Its flagship solution, the Cadi SmartSense System, includes the ThermoSensor—an innovative, coin-sized, battery-powered body-temperature sensor.

Equipped with active RFID tech, the ThermoSensor measures patients’ temperatures continuously and wirelessly transmits the data to central servers. The complete system—Cadi SmartSense Wireless Temperature Monitoring System—has earned CE medical certification and FDA clearance.

Clinical Trials & Hospital Deployments

Singapore General Hospital (SGH)

SGH adopted a variant of the SmartSense system for enterprise-wide patient location tracking. This deployment was integrated with the Allscripts Patient Flow Solution to optimize bed management from admission to discharge.

SGH’s efforts earned notable recognition:

• Microsoft Healthcare User Group Award 2010 for “Best Use of Clinical Records — Inpatient,” for combining Eclipsys Sunrise Patient Flow with SmartSense RTLS.

• Computerworld Honors Laureate 2010 for a Bed Management System orchestrated using Cadi’s RTLS and Allscripts software to enhance throughput, especially during pandemics.

Tan Tock Seng Hospital (TTSH)

TTSH was a pioneering adopter. Its journey included:

• December 2006: Full deployment of patient location tracking for ~1,200 inpatients using 2‑in‑1 SmartSense tags.

• December 2008: After a successful clinical trial, TTSH expanded to include both temperature monitoring and location tracking for all inpatients.

One illustrative scenario involved an 83‑year‑old patient (“Madam Lee”). A tiny wireless device pasted on her allowed nurses to monitor her temperature—without waking her up—enhancing comfort and safety.

An RFID Journal report noted in 2007 that TTSH affixed 3‑cm active UHF ThermoSensor labels to patients’ abdomens. The system demonstrated an accuracy within ±0.2 °C, comparable to ear, underarm, or oral thermometers. Data flowed wirelessly to SmartNode readers and onto servers, enabling near real-time charting via Cadi’s SmartSense Enterprise software.

Technology & User Experience

Sensor Placement & Hardware

According to the official user manual for the TSS‑900 ThermoSensor:

• It’s attached to the patient’s lower abdomen using hypoallergenic adhesive (e.g., 3M Tegaderm)—placed about 3 fingers below the navel.

• Specifications:

  • Measures every 30 seconds

  • Accuracy: ±0.2 °C (32–42 °C range)

  • Battery life: approx. 12 months continuous use

  • Size: 36 mm diameter, 11.6 mm thick, ~12 g weight

  • Fully water‑resistant

  • CE- and FCC-compliant

Upon activation, each sensor sends a unique ID and temperature to the SmartNode, which relays the data to central monitoring systems.

Clinical Validation

A clinical evaluation involving 109 children found that the ThermoSensor’s readings matched well with standard ear (Braun ThermoScan) and axillary thermometers.

Benefits & Impact

Nursing Workflow Efficiency

• Automatic readings free nurses from manually taking vitals, allowing them to prioritize patient care.

• In TTSH, this automation contributed to improved bed utilization, faster discharges, and better coordination across departments.

Patient Comfort & Care

• Continuous, non-disruptive monitoring ensures better patient rest—especially beneficial for sensitive or critical-care cases.

Operational Efficiency & Recognition

• Integration with patient flow systems led to international awards and benchmarks for smart hospital infrastructure.

Scalable & Sustainable

• Long battery life and repeatable use translate to low maintenance.

• Adhesive and waterproof design ensures reliability in busy ward environments.
