“…This is an important feature which improves the reliability of the system. Moreover, considering that the length of the wire affects the resulting electrical inductance, the proposed zigzag pattern increases inductance and, thus, improves sensor sensitivity as well as its resistance to interference from other electrical devices [30]. Furthermore, dimensions of the zigzag pattern, more specifically its length, angle, and width, are also determining factors in the resulting inductance [31].…”

Low back pain (LBP) is the most common work-related musculoskeletal disorder among healthcare workers and is directly related to long hours of working in twisted/bent postures or with awkward trunk movements. It has already been established that providing relevant feedback helps individuals to maintain better body posture during the activities of daily living. With the goal of preventing LBP through objective monitoring of back posture, this paper proposes a wireless, comfortable, and compact textile-based wearable platform to track trunk movements when the user bends forward. The smart garment developed for this purpose was prototyped with an inductive sensor formed by sewing a copper wire into an elastic fabric in a zigzag pattern. The results of an extensive simulation study showed that this unique design increases the inductance value of the sensor, and, consequently, improves its resolution. Furthermore, experimental evaluation on a healthy participant confirmed that the proposed wearable system with the suggested sensor design can easily detect forward bending movements. The evaluation scenario was then extended to also include twisting and lateral bending of the trunk, and it was observed that the proposed design can successfully discriminate such movements from forward bending of the trunk. Results of the magnetic interference test showed that, most notably, moving a cellphone towards the unworn prototype affects sensor readings, however, manipulating a cellphone, when wearing the prototype, did not affect the capability of the sensor in detecting forward bends. The proposed platform is a promising step toward developing wearable systems to monitor back posture in order to prevent or treat LBP.

“…In addition, planar eddy current sensors manufactured using PCB have been reported in literatures [12][13][14]. Therefore, design principles for CI probes can be easily taken into consideration when manufacturing such planar coils to make the final product suitable for both CI mode and eddy current mode.…”

“…Існуючий метод неруйнівного контролю не потребує спеціальної підготовки поверхні об'єкта контролю [6,7]. При контролі електропровідних матеріалів, такий метод схожий на вихрострумовий за своїми можливостями визначення параметрів контролю (визначення електропровідності, поверхневих та підповерхневих дефектів і т.…”
