Biomedical Signals Monitoring Based in Mobile Computing
ABSTRACT:
The main objective of this project consists in the development of a biomedical
instrumentation prototype for acquisition, processing and transmission of biomedical signals.
These biomedical signals are acquired and then processed with a microcontroller. After
processing, all data are sent to a communication interface that can send this information to a
personal computer or a cell phone.
The prototype developed, which is a digital blood pressure meter, is intended to allow
remote monitoring of patients living in areas with limited access to medical assistance or scarce
clinical resources. We believe that this development could be helpful to improve people’s quality
of life, as well as to allow an improvement in the government attendance indices.
This project uses regulated 5V, 750mA power supply. 7805 three terminal voltage regulator is
used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of
secondary of 230/18V step down transformer
