The role of sensors, big data and machine learning in modern animal farming
Suresh Neethirajan · 7 Jul 2020
Ever since man began domesticating animals several thousand years ago, we have always relied on our intuition, collective knowledge, and sensory signals to make effective animal production decisions. So far, this has helped us make significant gains in animal husbandry and farming. Together the growing demand for food and the advancement in sensing technology have…
The strategies of DNA immobilization and hybridization detection mechanism in the construction of electrochemical DNA sensor: A review
Jahwarhar Izuan Abdul Rashid, Nor Azah Yusof · 22 Sep 2017
In recent years, electrochemical deoxyribonucleic acid (DNA) sensor has recently emerged as promising alternative clinical diagnostic devices especially for infectious disease by exploiting DNA recognition events and converting them into an electrochemical signal. This is because the existing DNA diagnostic method possesses certain drawbacks such as time-consuming, expensive, laborious, low selectivity and sensitivity. DNA immobilization…
Refractive index sensor based on all-dielectric gradient metasurface
S. A. Rodionov, M. A. Remnev, В. В. Климов · 1 Feb 2019
A new type of a refractive index sensor based on all-dielectric gradient metasurface was proposed and analyzed with making use of the finite element method (FEM). A new method of optical data processing which is based on intensity distribution over several diffraction orders was suggested. The intensity sensitivity of 4450%/RIU and the phase sensitivity of…
