The ever increasing number of people who need continuous medical attention coupled with the rising costs of healthcare have triggered the concept of remote patient monitoring. This can be achieved using wireless sensor nodes attached to the human body. Such technology is mainly limited by the amount of available energy. Thus efficient power consumption estimation in the early stage of the design is...
This paper discusses the use of Wireless Sensor Networks (WSN) for low data rate and power constrained applications like precision agriculture. Studies of different WSN technologies were conducted and their utility in precision agriculture was evaluated. A ZigBee based sensor node was implemented and field tested. The Sensor Network was also simulated in network simulator (NS2.34) and various network...
A low power consuming intelligent monitor system of tire based on radio frequency technology is designed in this paper. The low consuming power unit, the measurement unit, the agreement of timestamp and the protocol of chain layers are presented in details. The main program flow charts of the measuring terminal and host terminal are given.
We present the design of an ultra-low power, wireless capacitance/temperature sensing device for continuous intraocular pressure monitoring. The device is wirelessly powered and demonstrates a power consumption of 2.3μW at 1.5V during continuous reading. The chip converts both capacitance and temperature to frequency using a time-interleaved relaxation oscillator, which modulates RF backscatter...
In the last years the number of papers related to wireless sensor networks has increased substantially. Most of them focus in raising issues as routing algorithms, network lifetime, and more recently, Multiple Input Multiple Output wireless networks. In contrast with all those studies, we present a practical application of wireless networks: The sensing of the pH and temperature for a fish farm. The...
