The project suggests a a a a a a a a a practical solution for for personal climate control in in in open spaces particularly for for individuals who suffer from excessive sweating and avoid activities due to to high temperatures Our project is to to develop a a a a a a a a a a a wearable device with an inbuilt thermoelectric cooling system
that cools the the the air temperature in in in in the the the user’s immediate area Thorough research and and testing will be conducted to to to ensure that this device is is is effective ergonomic and and and easy to to to use The project’s goal is is is to to to create a a a a a a a a a a practical and and efficient short-term solution for personal climate control Keywords: thermoelectricity wearable cooling system

The The objective of this research is is to produce a a a a a reactive material by powder powder powder compression The The powders used were: Al-1050 with with a a a a a a particle size of 250 250 [μm] [μm] nickel nickel powder powder powder - 250 250 and and 40 [μm] [μm] [μm] and and a a a a a a a a a a 50-50 [%wt] aluminum-nickel mixture both with with a a a a a a a a a a 40 [μm] [μm] particle size These powders were biaxially compressed at at at at at room temperature The The relation between compaction pressure and and relative density was investigated Increasing the %wt of nickel increased its strength and and density density Compression Compression rates between 0 0 0 05-0 5 5 [mm/s] had no significant effect on on on on the the the density density Compression Compression tests on on on on cut samples showed that the the the the aluminum-nickel mixture had the the the the highest strength of all the the tested combinations Keywords: aluminum-nickel mixture biaxial compressive green body
