Muhammad Fahad Farooqui's paper on inkjet printed flood sensor has been accepted for publication at the IEEE transactions on antennas and propagation​​. The title of the paper is "An Inkjet Printed Buoyant 3-D Lagrangian Sensor for Real Time Flood Monitoring".

Abstrace: A 3-D (cube-shaped) Lagrangian sensor, inkjet printed on a paper substrate, is presented for the first time. The sensor comprises a transmitter chip with a microcontroller completely embedded in the cube, and a 1.5λ0 dipole that is uniquely implemented on all the faces of the cube to achieve near isotropic radiation pattern. The sensor has been designed to operate both in air as well as water (half immersed) for real time flood monitoring application. The sensor  weighs 1.8 gm and measures 13mm x 13mm x 13mm, where each side of the cube corresponds to only 0.1λ0 (at 2.4 GHz).  The printed circuit board has also been inkjet printed on paper substrate to make the sensor light weight and buoyant. Issues related to the bending of inkjet printed tracks and integration of transmitter chip within the cube, have been discussed. The Lagrangian sensor is designed to operate within a wireless sensor network and field tests have confirmed that it can communicate up to a distance of 100 m while in air and up to 50 m while half immersed in water.
