Wireless body area network for cycling posture monitoring
This work presents the design and implementation of a wireless body area
network based on Bluetooth Low Energy (BLE) which enables the integration of
multiple sensor nodes into a smartphone-based system in order to monitor the
posture of cyclists. The wireless posture monitoring system presented in this
chapter obtains the orientation in space of each body segment in which the sensor
nodes are placed and calculates the trunk angle, the knee angle and the angle of
inclination of the road. This system collects raw sensor data from accelerometers,
magnetometers and gyroscopes and sends the data via BLE to an Android
smartphone, which plays the role of central station and performs the data
processing concerning the posture calculation. This chapter describes the
development of the hardware and software of the sensor nodes, which are based
on the CC2540 BLE system-on-chip, as well as the development of the Android
application. Experimental results concerning the measurement of the posture of a
cyclist are provided in order to validate the implementation.This work has been supported by FCT (Fundação para a Ciência e

Wireless hydrotherapy smart-suit network for posture monitoring
A wireless smart-suit network for monitoring body
kinetics, heart and respiratory rate during hidrocinesiotherapy
sessions is presented. Sensing modules composed by 3-axis
accelerometers, 3-axis magnetometers and interface electronics
are used to monitor the body kinetics. Heart rate is measured
using an ear clip infrared sensor and respiratory frequency is
measured with inductance plethysmography. The sensor network
is integrated in a swimming suit and data is transmitted in real
time to a base station using a 2.4 GHz RF transceiver.
Measurements of the rotation of shoulders, hips and spine are
performed with a resolution of less than 2 degrees. A new MAC
protocol for wireless sensing and actuation, LPRT protocol,
implemented in MICAz motes is used. Some of the characteristics
of the proposed protocol are low power consumption, real-time
support and loss intolerant traffic. The protocol uses contentionfree
operation and retransmission scheme and is very flexible and
has high throughput efficiency.Agência de Inovação (ADI

Body posture monitoring system
This project title is Body Posture Monitoring System. It involves both of the hardware and software construction to make this project complete successfully. This
project involves Medical in Engineering field which related to the human health. This involves the wearable device to give alertness to user about their posture especially when sitting and standing. This device consists of two part which is the back module that
contain sensor and wrist module that contain LED and Liquid Crystal Display (LCD). With the implemented circuit design, this device will produce light only at certain danger parameter which has been set in the software part. Nevertheless, the light will not interrupt
the user daily activity because it happens only in a short while. Furthermore, with the implement (LCD) screen technology, the user can monitor his postural rate. In
conclusion, user can decrease the risk of having the bad effect of poor body posture and can enjoy their healthy body posture
Development of a Wireless and Ambulatory Posture Monitoring System
The wireless and ambulatory posture monitoring system monitors the movement and posture change of the human body with respect to the g-line. It is crucial to monitor the posture health of the ophthalmologist who spends a prolonged period on the static sitting posture while operating on the slit lamp which leads to any painful experience. The motivation of the proposed system is to improve the ergonomics of the ophthalmologist on their working environment and reduce any occupational potential hazard which may prompt Work-Related Musculoskeletal Disorders (WMSDs). The proposed system also induced a wireless system by using XBee wireless units to reduce the use of the wire that may tangle on the study subject which causes any uncomfortable experience to the study subject during the human trial. Inertial Measurement Unit (IMU) sensor which consists of an Accelerometer, a Gyroscope and a Magnetometer is used to measure the angle of deviation of the body segment with respect to the g-line. The data is tabulated and presented into the graphical method to identify and extract the properties of the graph on each different static sitting posture which later are used for posture recognition
A wireless posture monitoring system for personalized home-based rehabilitation
We live in an aging society, an issue that will be exacerbated in the coming decades, due to low birth
rates and increasing life expectancy. With the decline in physical and cognitive functions with age, it is of the
utmost importance to maintain regular physical activity, in order to preserve an individual’s mobility, motor
capabilities and coordination. Within this context, this paper describes the development of a wireless sensor
network and its application in a human motion capture system based on wearable inertial and magnetic sensors.
The goal is to enable, through continuous real-time monitoring, the creation of a personalized home-based
rehabilitation system for the elderly population and/or injured people. Within this system, the user can benefit
from an assisted mode, in which their movements can be compared to a reference motion model of the same
movements, resulting in visual feedback alerts given by the application. This motion model can be created
previously, in a ‘learning phase’, under supervision of a caregiver.Project “AAL4ALL”, co-financed by the

A Low-Cost and Energy-Effcient Wearable Device For Posture Monitoring
Millions of Americans suffer every year from back problems, now imagine if there was a way to help track and prevent back problems. Our solution to this problem is PostureBot a device that will help its users to correct their back posture and maintain good back posture.In doing so this device can help elevate and prevent people from developing minor and serious back problems in their future
Healthy Sitting Behaviour Enhancement using a Smart Chair System
The aim of this paper is to present a smart chair prototype to monitor the sitting behaviour of people in wheelchair to re-educate them about long periods of time standing still and in the same position and giving them a feedback about this. The project is mainly focused on those who have been in a wheelchair for a short time. The sitting posture monitoring in the developed smart chair system can help or promote people to achieve and maintain healthy sitting behaviour, and prevent or reduce diseases caused by poor sitting behaviour, like bedsores (pressure ulcers)
