Electrosmart is an Android application which measures the radio-frequency electromagnetic waves emitting from various sources like mobile phones (cellular networks i.e., 2G, 3G, 4G, 5G), WiFi access points, Bluetooth devices, etc. [2] The app uses the antenna of mobile phones to calculate the pollution of waves and order them according to the power of that particular source.
An EMF meter is a scientific instrument for measuring electromagnetic fields (abbreviated as EMF). Most meters measure the electromagnetic radiation flux density (DC fields) or the change in an electromagnetic field over time (AC fields), essentially the same as a radio antenna, but with quite different detection characteristics.
In electrical engineering, electromagnetic shielding is the practice of reducing or redirecting the electromagnetic field (EMF) in a space with barriers made of conductive or magnetic materials. It is typically applied to enclosures, for isolating electrical devices from their surroundings, and to cables to isolate wires from the environment ...
These incorporate bandwidths and detectors as specified by international EMC standards. An EMI receiver may be based on a spectrum analyser to measure the emission levels of the DUT across a wide band of frequencies (frequency domain), or on a tunable narrower-band device which is swept through the desired frequency range.
Medipix-2, Timepix, and Medipix-3 are all 256×256 pixels, each 0.055 mm (55 μm) square, forming a total area 14.08 mm × 14.08 mm. Larger area detectors can be created by bump-bonding many chips to larger monolithic sensors. Detectors of sizes from 2x2 to 2x4 chips are commonly used.
