Summary
A novel Bluetooth antenna (BLEpatch) monitors respiration and aids contact tracing. Its unique design ensures robust performance near the body, adapting to breathing for enhanced wearable applications.
Area of Science:
- Electrical Engineering
- Biomedical Engineering
- Wearable Technology
Background:
- Respiration monitoring and contact tracing are crucial applications for wearable technology.
- Existing on-body antennas face performance challenges due to body proximity and movement.
- There is a need for robust and adaptive antenna solutions for continuous physiological monitoring.
Purpose of the Study:
- To propose and simulate a 2.4 GHz on-body Bluetooth antenna (BLEpatch) for respiration monitoring and contact tracing.
- To investigate the antenna's performance robustness at body proximity.
- To evaluate the impact of a compressible substrate on antenna performance during respiration.
Main Methods:
- Design and simulation of a 2.4 GHz patch antenna with a compressible foam substrate.
- Antenna performance evaluation in free space and on a human body model.
- Analysis of antenna parameters, including passband and gain, under simulated physiological conditions.
Main Results:
- The proposed BLEpatch antenna demonstrates robust performance at body proximity due to its patch structure.
- The compressible foam substrate enables the antenna to adapt to respiration-induced abdominal pressure changes.
- The antenna exhibits a passband of 2.36 - 2.57 GHz with a maximum gain of 8.2 dBi in the relaxed state.
Conclusions:
- The BLEpatch antenna is a promising solution for respiration monitoring and contact tracing wearables.
- The antenna's design offers resilience to body proximity and dynamic physiological changes.
- Further development could integrate this antenna into advanced wearable health and tracking systems.

1.1K
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,...

370
Pulse oximetry, or SpO2, is a non-invasive method for continuously monitoring arterial oxygen saturation (SaO2). This procedure involves attaching a probe or sensor to the patient's fingertip, forehead, earlobe, or nose bridge. The sensor works by detecting changes in oxygen saturation levels through light signals generated by the oximeter and reflected by the pulsing blood under the probe.
Purpose
Average SpO2 values are greater than 95%. If the readings fall below 90%, it indicates that...

Procedural Guide for Assessing Axillary Body Temperature using a Digital Thermometer:
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...

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...
