BIOMETRIC and BIO-MEDICAL based on Embedded System
WIRELESS POWER TRANSMISSION WITH SELFREGULATED OUTPUT VOLTAGE FOR BIOMEDICAL
IMPLANT
ABSTRACT:
An embedded system is characterized by real-time and multi-rate
operations define the ways in which the system works, reacts to events and
interrupts and schedules the system’s functioning in real time. It does so by
following a plan to control latencies and to meet deadlines. The different
operations may take place at distinct rates.
The user of an embedded device is often not even aware that a computer is
present in the device. The computer is used primarily to provide flexibility and to
simplify the system design. Unlike a PC, program code is usually stored in ROM
and not a hard disk drive. Typically, the end user does not develop new software
for the embedded device. With advances in VLSI technology, embedded systems
have become so inexpensive that they are found in most of today’s electronic
devices.
Since wireless power transfer technology (WPT) gains its popularity, broad
range of application and research are performed in the field of medical implantable
applications. In this paper, we review the technical status of WPT system applied
to medical implant devices.
As a practical application of this technology, the current achievements and
challenges of wireless capsule endoscopy are reviewed and analyzed, in view of its
design, functional requirement and related issues in WPT.

WPT application to artificial heart is also discussed. Based upon the
analysis, we propose a research directions and WPT consideration in designing a
WPT system for implantable medical applications.
PROPOSED SYSTEM:
Here we are going to see Medical Implantable Applications
using WPT (Wireless Power Transfer). AC supply will be given HF (High
Frequency) Transformer, so that Transformer can produce high magnetic flex in
the primary side.
It will be transferred to secondary side and using filters it is given to DC
regulator with help of regulator, supply will be given to Microcontroller. And heart
sensor will find the rate of heart beat, ECG sensor will record the electrical activity
of heart and temperature sensor is used to find the temperature of the person and
the sensor values will display in the LCD and we can monitor these values by
themselves.
