Journal ArticleDOI
A uW Backscatter-Morse-Leaf Sensor for Low-Power Agricultural Wireless Sensor Networks
Spyridon Nektarios Daskalakis,George Goussetis,Stylianos D. Assimonis,Manos M. Tentzeris,Apostolos Georgiadis +4 more
TL;DR: A novel, low-cost, and low-power system for leaf sensing using a new plant backscatter sensor node/tag is presented, which can result in the prevention of water waste (water-use efficiency), when is connected to an irrigation system.
Journal ArticleDOI
Ambient Backscatterers Using FM Broadcasting for Low Cost and Low Power Wireless Applications
Spyridon Nektarios Daskalakis,John Kimionis,Ana Collado,George Goussetis,Manos M. Tentzeris,Apostolos Georgiadis +5 more
TL;DR: A novel wireless tag and RX system that utilizes broadcast frequency modulated (FM) signals for backscatter communication and a theoretical analysis of the error rate performance is provided and compared to bit-error-rate measurements on a fixed transmitter-tag-RX laboratory setup with good agreement.
Journal ArticleDOI
A printed millimetre-wave modulator and antenna array for backscatter communications at gigabit data rates
TL;DR: A millimetre-wave modulator and antenna array for backscatter communications at gigabit data rates, created with inkjet printing, providing a bit rate of two gigabits per second and with a front-end energy consumption of only 0.17 pJ per bit.
Journal ArticleDOI
Four-PAM Modulation of Ambient FM Backscattering for Spectrally Efficient Low-Power Applications
Spyridon Nektarios Daskalakis,Ricardo Correia,George Goussetis,Manos M. Tentzeris,Nuno Borges Carvalho,Apostolos Georgiadis +5 more
TL;DR: A novel wireless tag is presented, which for the first time utilizes 4-pulse amplitude modulation technique to modulate the ambient backscattered FM signals in order to send data to a nearby low-cost software defined radio reader.
Proceedings ArticleDOI
Achieving Fully Autonomous System-on-Package Designs: An Embedded-on-Package 5G Energy Harvester within 3D Printed Multilayer Flexible Packaging Structures
TL;DR: A novel multilayer flexible packaging fabrication process using only additively manufacturing techniques including inkjet and 3 dimensional (3D) printing is proposed, paving the way for a multitude of novel miniaturized autonomous modules for wearable, IoT, and 5G applications.
