related works that are based on the BLE protocol for data gathering. We classified the studied contributions into two categories. The first category corresponds
to RHMS that control or sense one physiological patient data. The second category resembles the RHMS using multiple sensors to sense several physiological
data.
Mono-Sensing RHMS. In this subsection, we will analyze related works about
RHMS that sense and collect physiological information from a single sensor.
- Wearable Noncontact Armband for Mobile ECG Monitoring System: Rachim and all. [16] proposed to implement a mobile ECG monitoring
system using a wearable noncontact armband ECG signal. The proposed system
solved the problem of the previous healthcare heart devices which do not provide
patient’s information such as heartbeat, heart disease, and heart conditions. The
proposed system consists of capacitive-coupled electrodes fixed in an armband
which is more convenient (smaller) than systems with ECG sensors strapped to
the chest. The capacitive-coupled electrodes can sense bio-signals through the
clothes. According to the experimental results carried by the authors, the developed system can still function with different clothing thicknesses between the
sensors and the skin and when the user carries out various daily living activities.
Furthermore, the authors developed an Android application showing in real-time
the evolution of the ECG signal on a graph and analyze the sensed data for first
notifications making.
- Wireless Ring-Type Pulse Oximeter with Multi-detectors: The authors
of [17] conceived and developed a wireless finger ring-type pulse oximeter with
multi-detectors to monitor the blood oxygen saturation (SpO2). The developed
system contains (1) three optical probes to provide the light source and receive
the penetrated light that passes through the human tissue; (2) a wireless data
acquisition module containing a microprocessor (MSP430), a LED driving circuit, PD amplifier circuits and a wireless transmission unit. PD amplifier circuits
amplify and filter the received penetrated light. Therefore, the digitized penetrated light signal will be sent to the host system (that receive, display, store and
analyze the penetrated light signal) using a wireless transmission unit including a Bluetooth v2.0 module and a printed circuit board (PCB) antenna. The
monitoring program built in the host system will.
- Wireless Scale Based on the Bluetooth 4.0 Low-Energy: Huang and
all. [18] realized a low power and smart Bluetooth scale with a sensor chip
CC2540 monitored through a mobile application. The weight sensors produce
deformation and change their shapes when a patient ascend on the scale this
lead to a variation of the driven voltage. Therefore, these signals are amplified
and transmitted to an A/D converter.
- Muscule Activity Monitoring: Several systems integrating EMG sensors
to measure the electrical muscle activity and a BLE communication module
to transmit gathered data to a mobile phone. In this context, authors in [19]
