Development of the Second Generation Berry Impact Recording Device (BIRD II)

Abstract: To quantitatively measure the impacts during blueberry harvesting and post-harvest handling, this study designed the second generation Berry Impact Recording Device (BIRD II) sensor with a size of 21 mm in diameter and a weight of 3.9 g, which reduced the size by 17% and the weight by 50% compared to the previous prototype. The sensor was able to measure accelerations up to 346 g at a maximum frequency of 2 KHz. Universal Serial Bus (USB) was used to directly connect the sensor with the computer, removing the … Show more

“…109 An IS might be an ideal choice for impact studies such as capturing the shocks to fresh produce in a packaging or a sorting line. [110][111][112][113] At present, real-time monitoring of consignments in the supply chain involves remote acquisition of information on the proximity, temperature, humidity, and some gas concentrations during transit.…”

“…With the rapid development in accelerometer technology, miniature devices can be developed with all systems embedded in a single data logging device, and these can be even presented in the form of instrumented spheres (IS) in the shape of a fruit . An IS might be an ideal choice for impact studies such as capturing the shocks to fresh produce in a packaging or a sorting line …”

“…Fernando et al [21] note studies that use triaxial accelerometers and instrumented spheres similar in size to various fruit. The problem with the instrumented spheres is that the surface texture property does not necessarily mimic the fruit surface texture that affects the dynamics of the system [39]. Triaxial accelerometers provide a more accurate response in impact characterization when measuring in multiple orientations, because they enable calculation of the resultant acceleration.…”

“…This instrument uses a triaxial accelerator as a shock sensor that records acceleration and speed information. The first prototype was a 140 mm sphere, the second generation was an 89 mm sphere, and the latest version -called the impact recording device (IRD)-is a sphere with a diameter of 57 mm and a weight of 96 g (28) . There are also other devices with ellipsoid shapes that are used to evaluate impacts on potatoes (PTR 1100), onions (PMS-60), and berries (BIRD), among others (29)(30) .…”
