Design and construction of a Fruit Transducer for the Measurement of Impact Bruises on Fruits

Abstract

Fruit bruises has always been overlooked and its measurement left to human judgement which is prone to variability. Here, a fruit transducer which permits the measurement of bruise parameters such as bruise voltage, bruise drop height and bruise energy was designed and constructed. The device consists of a power supply, filter, preamplifier und amplifier circuit Testing carried out in Benue State, Nigeria shows the device is perfectly workable with bruise parameters such as damaging drop height, damaging bruise energy and damaging bruise voltage for Citrus cinensis measured as 160cm, 2.243 and 11.9V respectively.
