This paper presents the development of a network platform which allows connecting multiple individual wireless devices for transmitting bioelectrics and biomechanics signals for application in a hospital network, or continuous monitoring in a patient's diary life. The Zigbee platform development proposal was made in three stages: 1) Hardware development, including the construction of a prototype network node and the integration of sensors, (2) Evaluation, in order to define the specifications of each node and scope of communication and (3) The Zigbee Network Implementation for bioinstrumentation based on ZigBee Health Care public application profile (ZHC). Finally, this work presents the experimental results based on measurements of Lost Packets and LQI (Link Quality Indicator), and the Zigbee Platform configuration for Bioinstrumentation in operation.
