Smart sensors, which are created by combining
sensing materials with integrated circuitry are being considered
for several biomedical application such as a Glucoselevel,
Temperature, ECG etc. Practical usability of the majority of
current wearable body sensor systems for multiple parameter
physiological signal acquisition is limited by the multiple
physical connections between sensors and the data-acquisition
modules. In order to improve the user comfort and enable the
use of these types of systems on active mobile subjects, a
wireless body sensor system that incorporates multiple sensors
on a single node is proposed. The system must be suitable for
longer-term monitoring of the subjects, such as continuous
wear and autonomous operation up to several days without
replacement of the power source. Thus power consumption is a
major challenge in these applications.

A prototype WBSN system was built to verify the
design. The measurement results show that prototype
WBSN with the designed ASIC can operate efficiently
as expected. In addition to the work-on-demand
capability, the special passive standby mode offered by
this design shows great advantage in terms of the
standby power for the sensor nodes in the WBSN for
medical applications. key issues in WSBN / WSN, and
the application specific requirements have been
discussed. And then sensor node architecture with a
hybrid of active / passive RF transceivers is proposed.
Adopting the passive RF, the “real-time” demand in the
medical care purpose can be satisfied with no extra
energy induced in the sensor nodes, solving the
problems that trade off occurs between low-power and
“real-time” wakeup in WBSN. It is especially suitable
for long-term standby stimulus (or drug delivery) sensor
node in the medical application. In this paper, we
provided a implementation of an Integrated healthcare
network that combined the advantages of 802.15.4,
802.11 and mobile technologies for efficient remote
health monitoring and alarming.
