Effect of the shape and structure of maturity sensor’s plastic housing on its physico-mechanical properties

Abstract

This paper presents how the shape and physical structure of the connections affect the performance of the housing of maturity sensor. A two parts rectangular and a keg-shaped cylindrical configurations of plastic housings were sequentially tested for water, shock and load resistance. The tests revealed the weak ingress and shock resistance of the rectangular housing, in comparison with cylindrical one, where no serious defects were identified. Both types of housings performed well during the compression tests on all three sides, showing the bearing capacities from 0.6 to 2.11 kPa, which are equivalent to 65.3 and 165.3 kg of human mass. Based on the results, the study demonstrates an easy-to-handle workflow for generic testing and evaluation of maturity sensors housing. The proposed workflow may be applicable for other types of small-scaled electronic devices.
