Moni-Patch Temperature Monitoring Patch System, a non-invasive, continuous temperature monitoring device designed to estimate core body temperature by applying a Sensor to the neck.

This clinical accuracy validation study aims to verify the accuracy and repeatability of the Moni-Patch compared with an FDA-cleared continuous tympanic temperature monitoring device used as the clinical reference.

Main objectives of this study are; To verify that the Moni-Patch and the reference device(tympanic) demonstrate acceptable agreement, as defined by Bland-Altman Analyses (bias within ±0.4°C and limits of agreement between -1.0°C and 1.0°C).

To verify the consistency and repeatability of temperature measurements obtained from the Moni-Patch during continuous monitoring.

This study is conducted in accordance with ISO 80601-2-56:2017, which outlines definitions for temperature-measuring devices, age groups, required sample sizes, fever definitions, procedural flow, and statistical methods for clinical performance evaluation.

All subjects undergo temperature measurement using the reference device(Tympanic) and the investigational device (Moni-Patch Temperature Monitoring Patch System). The Moni-Patch Sensor is applied to the neck and paired with the Receiver, while the tympanic probe is positioned and sealed in the ear canal.

Each subject participates in a continuous 15-minute temperature monitoring session, during which both devices collect temperature values concurrently every 30 seconds.

Environmental temperature and humidity are also recorded during the session.

Inclusion Criteria:

• Age ≥ 7 years
• Agree to Sensor placement on the neck and ear

Exclusion Criteria:

• Ear conditions contraindicating tympanic probe; skin issues at placement sites
• Antipyretic use within 120 minutes; inability to position neck Sensor over carotid
• Inability to seal tympanic sensor; tympanic membrane not visually confirmed

De-identified instrument data will be analyzed by the Sponsor; no public IPD sharing is planned.
