SBN Wearables, Body Sensor Networks, Smart Portable Devices

Currently, there is a need for an immediate answer to a problem. There are useful ways and tools to help with that. This has taken Wearables, Body Sensor Networks, and Smart Portable Devices from nothing to ubiquitous. It has no signs of stopping down and an ever-increasing social effect. This article will analyze each issue of Wearables, Body Sensor Networks, and Smart Portable Devices.

1. Wearables

  • What are wearables?

It’s a little gadget that’s far more portable than a phone, and you can simply carry it on your person as an accessory. It is wearable, embedded in clothing, tattooed on the skin or implanted in the user’s body. Compared with mobile phones, it has many advantages, such as: lightweight and fast, low energy consumption, advanced interaction features, design simplification, etc.

It is a combination of an internet connection and a microprocessor. Therefore, you constantly receive real-time messages/notifications through it since it is connected to the Internet and immediately connects to mobiles and personal computers. It enables you to access data from anywhere.

Wearables are diverse and popular, such as fitness activity trackers, smartwatches, Bluetooth headsets, smartwatches, web-enabled glasses, virtual reality and augmented reality headsets.

  • Benefits of wearables

Monitoring: monitoring chips with built-in GPS to monitor children and the elderly.

Smart tattoos contain flexible electronic sensors to help monitor muscle function, sleep disorders, and heart and brain activity. In addition, it can be used to authenticate data transmission to smartphones or scanners to speed up processing processes.

Safety wearables: used as casual wear. However, when there is a threat or danger, it will issue a warning, turn on a loud alarm, and send a notification (a pre-set message, a recorded voice message with the location of where the device is located with built-in GPS) to someone (friend, family, police, or someone in the ecosystem using the device).

Improve health: helps you keep track of your daily activities, such as how long you sleep, your heart rate, and the number of steps you take. From there, it will analyze trends and give advice on activities.

Smartwatches: it will be synced with your smartphone. It helps you to receive/send notifications, emails, messages, and phone calls. It also integrates fitness trackers. At the same time, it helps to monitor and detect diseases early so that there is better treatment for each individual.

Portable and hands-free: with its compact and portable size, it helps to perform operations quickly.

  • Real-life Examples of wearables

  • Future of wearables

The combination of miniaturized microprocessors, high-speed data transfer and mobile networks is driving the growth of wearables.

In the future, towards the development of specialized and practical products.

Wireless charging would be a good solution to improve the battery life of current wearables. Batteries can be charged from sources such as solar energy, body heat and movement into power. When the batteries of today’s devices can only be used for almost a day.

        Measure data accuracy: improves the accuracy of the device. Especially in healthcare applications, the collected data must be of optimal accuracy before the analysis is meaningful.

Security and privacy: data is not encrypted and is transmitted via Bluetooth or Wi-Fi connections. In the future, data needs to be more secure, especially personal information. The adjustment of the security protocol in the D2D network needs to be researched and developed.

Authentication: The microchip uses a combination of radio-frequency identification (RFID) and near-field communication (NFC) technology used to uniquely identify users instead of usernames and passwords. This also integrates features such as helping users make payments and unlocking.

Lower visibility: this will make devices look like jewelry, clothing, patches, or straps.

Use machine learning in data collection and analysis.

Data transmission: using 5G and other technologies to increase transmission speed. Moving data storage, processing, and management from the centralized cloud to edge computing enables real-time data collection and processing, enabling faster and more efficient responses. Compressive sensing helps to optimize energy consumption and efficient bandwidth. These are the 2 most important elements in wearables.

Localization: wearable devices mainly rely on wireless networks (BLE, Wi-Fi, UWB) which are vulnerable to Non-Line of-Sight (NLOS), multipath propagation, scattering, diffraction, and reflection leading to information transmission incorrect. In the future, there will be a need for technologies to improve this situation.

2. Body Sensor Networks

    • What are Wireless Sensor Networks?

Wireless Sensor Networks (WSN) are advancements in energy storage, sensor design, and wireless communication. It helps to monitor many environmental factors, such as magnetic field, tilt and vibration, light intensity, barometric pressure, humidity, and temperature.

Figure 8: Smart Dust defense project allows to monitor enemy movements secretly (source: Smart Dust Could Ramp Up Internet of Things in Higher Education | EdTech Magazine (edtechmagazine.com))

        WSN was developed based on an open-source called Tiny Microthreading Operating System (TinyOS), which is an energy efficient operating system. TinyOS performs controlling power dissipation, routing decisions, and sensor measurements.

WSN applications are divided into 3 categories: monitoring objects, monitoring environments, and monitoring the interaction of these objects with environments.

  • Overview Body Sensor Networks

The Body Sensor Network (BSN) is the attachment of sensors to the surface of the body as well as implanting them into tissues. It contributes to the establishment of a consistent strategy for ubiquitous monitoring by establishing a standard.

Figure 9: An example of Body Sensor Network (source: (PDF) An Efficient Next Hop Selection Algorithm for Multi-Hop Body Area Networks (researchgate.net))

The architecture of the BSN will include a number of sensors (battery, wireless transmitter, a small processor) that are attached to the body and connected to the hospital, office and home. The nodes of the BSN collect data from the sensors they connect to, do low-level processing of the data, and then wirelessly transmit the information to the Local Processing Unit (LPU) for processing and consolidation. Finally, the data is sent to the central monitoring server via (3G, GPRS, Bluetooth or wireless LAN).

  • The function of Body Sensor Networks

Wireless BSNs provides a framework for establishing such a health monitoring system and diagnostic tools. It will provide dramatic, important information.

Monitoring Patients with Chronic Disease: detect early signs of chronic diseases (heart through ECG, high blood pressure, diabetes mellitus) to prevent the risk of stroke. As well as monitoring the patient’s response and progress to different treatments.

Monitoring Hospital Patients: automate patient monitoring from anywhere. Monitoring and detecting problems that occur after surgery is very important. This also provides a streamlined and optimal process for receiving and dealing with the patient’s condition.

Monitoring elderly patients: this helps provide the elderly with adequate and timely medical help. The benefits are reduced mortality, morbidity and the need for hospitalization.

Some of the other benefits of BSN also apply to areas including security, military and sports.
