Printed RFID Humidity Sensor Tags for Flexible Smart Systems

Radio frequency identification (RFID) and sensing are two key technologies enabling the Internet of Things (IoT). Development of RFID tags augmented with sensing capabilities (RFID sensor tags) would allow a variety of new applications, leading to a new paradigm of the IoT. Chipless RFID sensor technology offers a low-cost solution by eliminating the need of an integrated circuit (IC) chip, and...

All Inkjet - Printed B Field Sensor †

This paper presents the realization and the experimental characterization of a low cost inkjet-printed DC magnetic field sensor. The device consists of a thin flexible cantilever beam operated at its first resonance frequency by the interaction between the target magnetic field and an AC current flowing through a coil printed on the beam. A resistive readout strategy is implemented by a printed...

Intelligent Humidity Sensor for - Wireless Sensor Network Agricultural Application

Wireless Sensor Networks (WSN) is now widely used in precision agriculture applications. Sensors play an important role in WSN. The traditional humidity sensors employed in the agriculture have a drawback that they acquire a large amount of data which is to be transmitted or processed. Whereas the intelligent sensor proposed in this paper uses a conventional sensor and an embedded processor tha...

An Adaptive LEACH-based Clustering Algorithm for Wireless Sensor Networks

LEACH is the most popular clastering algorithm in Wireless Sensor Networks (WSNs). However, it has two main drawbacks, including random selection of cluster heads, and direct communication of cluster heads with the sink. This paper aims to introduce a new centralized cluster-based routing protocol named LEACH-AEC (LEACH with Adaptive Energy Consumption), which guarantees to generate balanced cl...
