“…Katmanlı üretim yoluyla sensör entegrasyonu için çeşitli endüstriyel amaçlar tanımlanabilir: Bireylere özgü, özellikle tıp alanında, kişiselleştirme devrimi için, bir hastanın spesifik anatomisine yönelik gelişmiş biyomekanik cihazları tamamen kapalı RFID etiketi ile üretmek mümkündür [11]. Örneğin, sensör verileri, stabiliteyi iyileştirmek için implantların ve kemikli yapıların bağlantısını ayarlayabilir [18]. Ek olarak, entegre sensörler, makine parçası endüstrisinde bakımı tahmin etmek için [19] ve proses sıcaklığını ve aşınmayı izlemek için metal şekillendirme araçlarında [15] uygulama bulabilmektedir.…”

Bu derleme makalesi, katmanlı imalatta (Kİ) sensör entegrasyonuna odaklanmıştır. Devrim yaratma potansiyeline sahip katmanlı imalat, ürün tasarımı ve malzemelerinde benzeri görülmemiş bir esneklik sunar. Ayrıca Kİ, montajı yalnızca tek bir bileşenle mümkün kılarak diğer üretim yöntemlerinden ayrılmaktadır. Bu özellik, sensörü üretim sürecinde doğrudan entegre etmeyi mümkün kılmaktadır. Sensör entegrasyonu geleneksel üretim yöntemleriyle istenen mükemmellikte yapılamamaktadır. Katmanlı imalatla üretilen sensör entegreli parçalar geniş bir uygulama alanına sahiptir. Özellikle Kİ uygulamaları ile endüstri 4 çerçevesinde biyomedikal, otomotiv ve havacılık endüstrilerinde uygulanabilmesi ile kilit unsurların olabileceği yenilikçi bir çok alanda kullanım alanı oluşturabilecektir.

“…The components described include ball bearings, gears, hinges, and screws. In [4], the authors describe a general method for the design and integration of sensors and actuators in Ti6Al4V parts produced with AM. The L-PBF process is used to integrate an electric coil that can be used as a sensor or actuator into a femoral hip stem.…”

The incorporation of sensors into mechanical components is experiencing growing capabilities, thanks to emerging fabrication technologies such as metal additive manufacturing (AM). The functionalization of components with sensors has several applications in structural and performance monitoring, as well as failure prediction in prognostics and diagnostics operations. In this paper, a customized laser powder bed fusion (L-PBF) process is developed for embedding stand-alone sensors (and/or electronics, connectors, cables, etc.) into metal parts during the AM growth process. The method is based on interrupting and restarting the micromelting process after the sensor has been positioned. Finally, the integration process is used to fabricate a brake caliper with an embedded thermal sensor. The sensing performance is then validated on the assembled hydraulic braking system, with the aim of monitoring the thermal profile in working conditions.

“…Structural dynamics measurement methods as a field of acoustics represent a promising approach for a feedback-free analysis. The transferability of experimental acoustic analysis to medical engineering problems has already been demonstrated in various studies [ 30 , 31 , 32 , 33 , 34 , 35 ], with particular focus in [ 36 ] on the special features of the application of structural dynamics analyses to biological specimens. Most of the application of acoustic measurement methods to biological specimens follows the objective of parameter identification, e.g., the acquisition of modal parameters and a subsequent adaptation of simulation models to increase the prediction accuracy [ 37 , 38 , 39 , 40 ].…”

The wear comfort of a prosthesis is of great importance for amputee patients. The wear comfort can be affected by changes in the interface between the residual limb and prosthesis socket, which can be caused by time-dependent volume fluctuations of the tissue, leading to unwanted local pressure marks. The basis to ensure time-independent wear comfort of a prosthesis is to identify these changes. Common techniques for identifying these variations have a negative impact on the sensitive interface between the residual limb and prosthesis. The following paper contains a proof of concept for the detection of local pressure marks without affecting the described interface using structural dynamics measurements, exemplarily shown at a prosthetic socket for transfemoral amputees in a test bench scenario. The dynamical behaviour of the investigated system is analysed in the form of frequency response functions acquired for different pressure locations and preloads using an impact hammer for excitation and a triaxial acceleration sensor. The frequency response functions show major changes for the various boundary conditions with respect to their frequency-dependent compositions. The results demonstrate how the utilised method enables the identification of changes in local pressure marks regarding the variation of position and magnitude.
