Equipments Used to Measure Body Temperature

Equipments Used to Measure Body Temperature

Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...

Temperature Measurement Sites

Temperature Measurement Sites

A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Background:

Accurate temperature measurement is critical across industrial, scientific, and medical fields.
Existing temperature sensors face limitations in sensitivity, resolution, and response time for demanding applications.
Fiber optic sensors offer potential for high performance and remote sensing capabilities.

Purpose of the Study:

To propose and demonstrate a novel, highly sensitive fiber optic temperature sensor.
To enhance temperature sensitivity by utilizing the Vernier effect in a double-cavity configuration.
To develop a robust, simple, and reconfigurable sensor for practical applications.

Main Methods:

Fabrication of a double-cavity Fabry-Perot interferometer (DCFPI) using a polymer cap on a single-mode fiber connector.
Optimization of the air cavity length (L) and polymer cap thickness (L) to induce the Vernier effect.
Packaging the DCFPI in a movable mount for adjustable air cavity length and protection.

Main Results:

Demonstration of a DCFPI with significantly improved temperature sensitivity.
Achieved a temperature sensitivity of up to 39.8 nm/°C, outperforming standard polymer-capped fiber Fabry-Perot interferometers (PCFPI).
The DCFPI sensor is robust, easy to fabricate, and allows for simple adjustment of the air cavity.

Conclusions:

The proposed DCFPI sensor effectively enhances temperature sensitivity through the Vernier effect.
This technology offers a promising solution for high-sensitivity temperature monitoring in various demanding environments.
The sensor's simple design and robust packaging facilitate its practical implementation and manipulation.
