November 2019 doc. : IEEE 15 -19 -0559 -00 -0 vat Introduction q Research on electronic healthcare (e. Health) systems has increased dramatically in recent years. q e. Health represents a significant example of the application of the Internet of Things (Io. T), characterized by its cost effectiveness, increased reliability, and minimal human effort in nursing assistance. q The remote monitoring of patients through a wearable sensing network has outstanding potential in current healthcare systems. q In recent times, internet of things (Io. T) has conveyed substantial potentiality in electronic healthcare (e. Health). q Such a network can continuously monitor the vital health conditions (such as heart rate variability, blood pressure, glucose level, and oxygen saturation) of patients with chronic diseases. Low-power radio-frequency (RF) technologies, especially Bluetooth low energy (BLE), play significant roles in modern healthcare.

November 2019 doc. : IEEE 15 -19 -0559 -00 -0 vat Limitation in RF q RF spectrum is mostly licensed and regulated. q Some of the medical devices are sensitive to electromagnetic radiation. q The effect of the radiation on human health is also considerable. q As RF-based technologies offer omnidirectional communication, the security is a matter of concern.

November 2019 doc. : IEEE 15 -19 -0559 -00 -0 vat OCC q The limitations of RF can be mitigated using the optical spectrum. q Optical camera communication (OCC) is a promising candidate in this regard. q OCC uses an LED array to transmit data and a camera to receive data. q The received images by the camera are sampled to decode the transmitted message. q The LED array can be used to transmit the bio-signals to the remote monitor using a monitoring camera.

November 2019 doc. : IEEE 15 -19 -0559 -00 -0 vat Opportunities q OCC can be used in remote health monitoring of patients with chronic diseases. Herein, a patch-based device is utilized. q The patch is attached in the patient’s body. q The LED array is mounted in the patch circuit. q The healthcare signal is collected using a bio-sensor. q The signal is then amplified and eventually go through different filters. q Afterwards, an analog-to-digital converter digitalize the signal and mount it to the patch circuit. q The main advantage of this technology is the possibility of utilization of existing surveillance cameras to receive the bio-signals.

November 2019 doc. : IEEE 15 -19 -0559 -00 -0 vat Challenges q The patch should be built in a manner that it does not hamper the natural movement of the patients. In this regard, the size and the weight of the patch device can be a matter of concern. q As the size of the LED is small, the communication range will be small as well. Although it won’t be a serious problem for a small hospital-room scenario, the implementation of the system will be a great challenge when multiple patients will be needed to be monitored in a large room. Multipleinput multiple-output (MIMO) technique can be a solution to this problem. q For a mobile patient, the low data rate of the OCC system can be considered as a significant problem.
