“…The piezoelectric effect is suitable to such applications because it is able to convert dynamic mechanical deformation into electric charge. Typically, piezoelectric strips/threads or films are woven into, or glued on top of, the fabric to form a sensor [1,2]. However, the woven approach restricts the sensor orientation and in both cases sensor performance is determined by the movement of the fabric itself.…”

Abstract-This paper reports a novel process for realising freestanding piezoelectric cantilevers printed on fabric for potential use as a wearable sensor. Piezoelectric cantilever structures were fabricated by screen printing a piezoelectric stack on top of a structural layer that is supported by a sacrificial material during printing. The sacrificial layer was subsequently removed in an oven at 160 °C for 30 minutes which is sufficient to fully release the cantilever beam from the substrate. The samples were polarised by applying an electric field across the piezoelectric stack. Testing on an electromechanical shaker shows that the cantilevers have resonant frequencies at 390 and 260 Hz for beam lengths of 12 and 15 mm, respectively. The beams produced maximum outputs of 38 and 27 mV at an acceleration of 11.76 m/s 2 , respectively.

Son yıllarda küresel piyasada tekstil ve giyim sanayi, geleneksel tekstil ürünlerinden, bilgiyi adapte eden ve dolayısıyla yeni ve katma değeri yüksek akıllı tekstillere doğru kaymaya başlamıştır. Bu durum tekstil mühendisliğinin, kimya, elektronik ve malzeme bilimi gibi diğer bilimlerle, multidisipliner bir çalışma alanını oluşturmuştur. Sensörler, akıllı tekstiller alanının önemli bir bölümünü oluşturmaktadır ve geleneksel tekstillere fark yaratacak gelişmeleri içermektedir. Bu makalede akıllı kumaş sensör çeşitleri ve literatürdeki uygulamaları ele alınmıştır.

“…Such a garment would allow users to be given directions in a building, maintenance workers to be automatically shown blueprints for their current room, or users to automatically map existing structures. The user's body position is measured by a set of piezoelectric strips woven into the clothing; by measuring the deformation along tens of strips, the physical configuration of the user's body can be detected [32]. The user's activity, such as walking upstairs, climbing a ladder, or walking on a flat surface, can be determined [32], [33].…”
