Abstract
Wearable bioinstrumentations already help medical personnel to diagnose many life-threatening conditions. However, because of their complexity and size, bioinstrumentations are currently available mostly in hospitals. Presently, few patient monitoring devices are designed for :applications where portability, simplicity, and low cost are important. In this project, ECG and temperature sensors are integrated into a snug fitting T-shirt. A data acquisition unit, integrated into the T-shirt ( composed of a microcontroller, power regulators, and analog signal filters) is used to collect and transmit sensor information to the handheld unit. An internal microcontroller is used to digitize data from the biosensors and to package it for transmission to a portable handheld unit. The T-shirt circuit is kept lightweight by excluding a power source, such as a battery pack. A handheld, battery powered, telemetry display unit is used to transmit power to the data acquisition unit and receive biosensor readings from it. A 1.9 MHz RF carrier wave is employed to transmit power wirelessly. The handheld unit collects the data received from the radio link with the: T-shirt, interprets it, and displays it on an LCD.
