Abstract

Within this work, a microgripper based on a hot–cold arm principle was tested to give a greater understanding of the associated heat dissipation methods. Experiments were conducted in air at atmospheric and sub-atmospheric pressure, and in helium, argon and helium at sub-atmospheric pressure. The change in deflection, when using gases with different thermal conductivities and at varying pressures showed the significance of conduction through the atmosphere. The experimental results were found to verify a theoretical model created previously by this group, and a further model developed independently; both predicted the deflection that a given current would cause.
