Implementation of wireless data transfer to photoplethysmographic measurements

Abstract

This article deals with the implementation of wireless data transfer in biomedical applications concretely in photoplethysmography. It deals with the application of a Bluetooth module for data transfer to computer where further signal processing can be performed. The work describes a use of microcontroller serving for data flow control, communication and analog signal digitalization using integrated analog to digital converter. The article involves also photoplethysmographic sensor and hardware design description.
