In the modern and demanding, world, whether in the line of science, industry, or for day to day
activities, sensing of the environmental parameters, is important and in many cases, even vital. Sensors
have been created throughout the years, taking advantage of a great variety of physical and chemical
properties. As the demand for more sensitive and responsive sensors grows, while keeping the devices
as small and low-cost as possible, multiple sensing principles and materials are researched and tested.
When it comes to Relative Humidity Sensing and in most cases the fabrication of flexible sensors, the
family of two dimensional materials, have been the focus of many researchers and industrialists, due to
their superior optical and electrical properties, small sizes and in many cases, cheap production. The
aim of this thesis is, to test the fabrication of sensors, using MnPS3 few and single-layers, extracted
from bulk synthetic crystal, with the method of Liquid Phase Exfoliation, following up a similar work,
on NiPS3 based sensors. The main focus of this work, is, after checking the sensing ability of the developed devices, the electrical characterization of two sensors, fabricated with a difference in the
sonication power used to exfoliate the material, measuring of some basic parameters of these sensors,
in order to compare them with other sensors recently created and Electrochemical Impendence
Spectroscopy measurement, which could allow to understand the way the sensor works and its working
principle, by indicating an equivalent circuit, with known passive elements.
