Thermosensation01:43

Thermosensation

32.2K
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

Assessing Body Temperature - Tympanic membrane01:14

Assessing Body Temperature - Tympanic membrane

800
Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...

Equipments Used to Measure Body Temperature01:13

Equipments Used to Measure Body Temperature

1.3K
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,...

Area of Science:

  • Optics
  • Fiber Optics
  • Sensor Technology

Background:

  • Mach-Zehnder interferometers are sensitive to environmental changes.
  • Fiber optic sensors offer advantages in harsh environments.
  • Improving temperature sensitivity in fiber optic sensors is crucial for various applications.

Purpose of the Study:

  • To design and demonstrate a novel fiber optic temperature sensor.
  • To enhance the temperature sensitivity of a Mach-Zehnder interferometer.
  • To investigate the effect of thermal-sensitive coatings on sensor performance.

Main Methods:

  • A Mach-Zehnder interferometer was constructed using cascaded single-mode fiber (SMF) and thin-core fiber (TCF).
  • Mode field mismatch between SMF and TCF excited cladding modes, forming the interferometer.
  • Thermal-sensitive materials (polydimethylsiloxane and ultraviolet glue) were coated onto the TCF surface.

Main Results:

  • The uncoated TCF sensor exhibited a temperature sensitivity of 32.0 pm/°C.
  • Coating with polydimethylsiloxane increased sensitivity to 90.0 pm/°C (approx. 3x).
  • Coating with ultraviolet glue increased sensitivity to 166.8 pm/°C (approx. 6x).

Conclusions:

  • The designed fiber optic Mach-Zehnder interferometer sensor demonstrates significantly enhanced temperature sensitivity.
  • UV glue coating provides a substantial improvement in temperature sensitivity compared to polydimethylsiloxane and uncoated sensors.
  • The sensor's compact structure, robustness, and high sensitivity make it suitable for industrial and defense applications.
