Summary
Optical wireless technology offers a secure, low-cost alternative to radio frequencies for wearable healthcare devices. This system effectively transmits accelerometer data for remote patient monitoring in hospitals.
Area of Science:
- Biomedical Engineering
- Wireless Communication
- Optical Technologies
Background:
- Hospitals are susceptible to electromagnetic interference, necessitating alternative communication methods.
- Radio frequency devices contribute to electromagnetic pollution in patient environments.
- Wearable devices offer potential for remote patient monitoring, but require reliable communication.
Purpose of the Study:
- To explore optical wireless technology for wearable healthcare devices.
- To assess the feasibility of optical wireless links in hospital environments.
- To develop and evaluate a custom wearable device for post-stroke patient activity supervision.
Main Methods:
- Development of a custom wearable device using commercial components.
- Transmission of accelerometer data via optical wireless links.
- Experimental evaluation of packet loss based on the number of ceiling-mounted receivers.
Main Results:
- Optical wireless links demonstrated effective data transmission for wearable healthcare applications.
- Packet loss was analyzed as a function of receiver quantity, indicating performance scalability.
- The system proved viable for mobile remote monitoring of post-stroke patients.
Conclusions:
- Optical wireless communication is a suitable technology for reducing radio frequency use in healthcare settings.
- The developed wearable device and optical system can support remote monitoring of patient physical activity.
- Performance can be theoretically predicted based on receiver deployment, facilitating system design.

The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.

An integrated healthcare system (IHS) is a set of organizations that provides for or arranges to provide coordinated and continuous service to a defined population. The IHS takes responsibility for that particular population's health status and outcome, both clinically and fiscally. An integrated healthcare system is a well-organized, well-coordinated, and collaborative network. The integrated delivery system is a network that connects different healthcare providers to deliver organized,...

Electronic Distance Measuring Instruments (EDMs) are essential tools in modern surveying, offering precise distance measurements by emitting electromagnetic signals and calculating the time required for these signals to travel to a target and return. Two primary types of signals are used in EDMs — light waves and microwaves — each suited to specific environmental and distance requirements. Light-wave-based EDMs utilize either infrared or laser light, providing high accuracy over...

Sharing information, concepts, and emotions to foster mutual understanding is communication. The sender, recipient, and transaction must be considered in this manner. The sender is the person who shares the message, the recipient is the person who receives and understands the message, and the transaction is the method used to deliver the message and the variables that affect the communication's context and surroundings. The nurse-client connection is built on therapeutic communication.

At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is...
