A miniaturized wireless blood pressure sensor uses capacitive coupling to transmit data and inductive powering to operate. The sensor consists of two small plates connected by a thin wire that is only 5mm thick and transmits data using a 6.4 microsecond bit length, consuming an average of 20.5 microwatts of power in air and 2.85 milliwatts when tested in phantom material.
A wireless body area network (WBAN) is a special purpose sensor network designed to operate autonomously to connect various medical sensors and appliances , located inside and outside the body.

Recent developments and technological advancements in wireless communication, Micro Electro Mechanical Systems (MEMS) technology and integrated circuits has enabled low-power, intelligent, miniaturized, invasive/non-invasive micro and nano technology sensor nodes strategically placed in or around the human body to be used in various applications, such as personal health and fitness monitoring, emergency response and device control. Sensor nodes comprised of one or more sensor devices, a micro-controller unit (MCU), and a radio transceiver that eliminates the need for wires to communicate with the coordinator node in order to transfer the collected data. The aim of WBAN's is to simplify and improve speed, accuracy, and reliability of communication of sensors/actuators within, on, and in the immediate proximity of a human body.
The purpose of this presentation is to introduce the Body Area Network technology. At the beginning I have discussed the history and development of Body Sensor Network and how that grew into the more general concept of BAN. MobiHealth as a mature example of MBSN technology has been explained. I then continued on to take a look at a case study involving MobiHealth and the monitoring cardiac data. I concluded the paper by looking at some challenges related to BAN. We covered signal and path loss in the human body and some of the challenges associated with communication and power within the human body. This ppt demonstrates usability and the fusion of cutting edge technology and how it is shaping wearable technology.
This is a presentation of our final year project of Biomedical Engineering course on Cuffless blood pressure monitoring. A new technology recently developed. We have tried to develop a model for the same.

Design of a miniaturized wireless blood pressure sensing interface using capacitive coupling
1. Design of a Miniaturized Wireless Blood Pressure Sensing Interface
Using Capacitive Coupling
Abstract:
This paper presents the implementation of a miniaturized wireless blood
pressure sensor interface. The system uses capacitive coupling in order to
transmit the data, as well as wireless inductive powering. Designed for a
bit length of 6.4 μs, the average power consumption of the device has been
measured to be 20.5 μW and 2.85 mW in air and phantom material,
respectively. The miniaturized sensor interface circuit consists of two plates
with a diameter of 2.5 cm, which are connected by means of a thin wire; the
device's maximum thickness is 5 mm.
