Summary
This study introduces DigiAID, a wireless Body Sensor Network (BSN) for cost-effective remote health monitoring. It optimizes energy efficiency by adapting power levels based on body movement and data transmission needs.
Area of Science:
- Biomedical Engineering
- Health Informatics
- Wireless Sensor Networks
Background:
- High costs of traditional medical facilities hinder access, especially in developing regions and during emergencies.
- Electronic health systems, particularly Body Sensor Networks (BSN), offer a promising alternative for accessible healthcare.
- Existing wired BSN solutions like DigiAID face user acceptance challenges due to cumbersome wiring.
Purpose of the Study:
- To develop and evaluate a wireless BSN (WBSN) platform, DigiAID, addressing limitations of wired systems.
- To analyze the impact of body movements on wireless data transmission and network topology in WBSN.
- To propose an energy-efficient dynamic power control algorithm for WBSN.
Main Methods:
- Comparison of wired DigiAID with commercial Hexoskin through real-world activity measurements.
- Characterization of a novel wireless DigiAID platform for WBSN.
- Comprehensive evaluation of body movement effects on WBSN data transmission and topology at various power levels.
- Development and testing of a dynamic power control algorithm.
Main Results:
- The wired DigiAID demonstrated viability but highlighted user discomfort due to wires.
- Wireless DigiAID platform was successfully developed and characterized.
- Body movements significantly impact WBSN data transmission and network topology.
- The proposed dynamic power control algorithm achieved substantial power savings across body-worn nodes.
Conclusions:
- Wireless DigiAID offers a viable, user-friendly alternative for remote health monitoring.
- Understanding and managing the impact of body movements is crucial for reliable WBSN operation.
- The developed dynamic power control algorithm enhances energy efficiency in WBSN, making it more practical for long-term use.

16.1K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

01:29Reliability and Validity
13.7K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

4.5K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

01:13Household Wiring And Electrical Safety
1.6K
Companies that supply power to most modern households use three conductors, typically called a three-wire line. While one is neutral, the other two are both at 120 V but with opposite polarity, giving a voltage of 240 V between them. With a three-wire line, high-power appliances that require 240 V, such as electric stoves and clothes dryers, are linked between the two hot lines. 120 V appliances can be connected between the neutral and either of the hot lines. The neutral side, which is always...

4.5K
Consider two parallel straight wires carrying a current of 10 A and 20 A in the same direction and separated by a distance of 20 cm. Calculate the magnetic field at a point "P2", midway between the wires. Also, evaluate the magnetic field when the direction of the current is reversed in the second wire.
