This proposal is concerned with the research and development of new manufacturing and assembly methods that add electronics functionality to textiles. Textiles are ubiquitous and are used, for example, in clothing, home furnishings as well as medical, automotive and aerospace applications. Textiles are one of the most common materials with which humans come into contact, but, at present, their functionality is limited to their appearance and physical properties. There is considerable and growing interest in SMart and Interactive Textiles (SMIT) that add electronic functionality to textiles. SMIT offer a far greater range of functionality that can include sensing, data processing and interaction with the user and, as a result, can be applied in a vast range of applications potentially wherever textiles are present. The overall objective of the research is to develop new manufacturing assembly methods that enable the reliable packaging of advanced electronic components (e.g. microcontrollers) in ultra-thin die form within a textile yarn. The programme of research will investigate approaches for mounting the ultra-thin die onto thin flexible polymer films strips that contain patterned conductive interconnects and bond pads. Individual die will be located on the strip and conductive tracks on the plastic substrate will them together forming a long, very thin, flexible circuit or filament. The filaments will then be surrounded by classical textile fibres (e.g. polyester, cotton, wool, silk) and connected to conductive wires to form an electronic yarn (EY) that will, essentially, appear to be a standard textile yarn but which has embedded within it, circuitry and components. The ultimate goal is to incorporate these EYs into the textile in such a way as to protect the electronic components and interconnects from the rigours of use whilst maintaining the feel, drape and breathability of the textile. A key aspect of the technology is the use of ultra-thin die which are highly flexible and, together with a rectangular footprint, will minimise the profile of the die within the filament. This will then serve to reduce the impact on the yarn making the electronics virtually invisible and minimising yarn diameter.

这项提议涉及研究和开发新的制造和组装方法，为纺织品增加电子功能。纺织品无处不在，例如，用于服装、家居以及医疗、汽车和航空航天应用。纺织品是人类接触到的最常见的材料之一，但目前，它们的功能仅限于外观和物理特性。人们对为纺织品添加电子功能的智能交互纺织品(SMIT)有相当大的兴趣，而且兴趣越来越大。SMIT提供了范围更广的功能，可以包括传感、数据处理和与用户的交互，因此可以应用于广泛的应用，可能是在任何存在纺织品的地方。这项研究的总体目标是开发新的制造组装方法，使先进的电子元件(如微控制器)能够可靠地封装在纺织纱线内的超薄模具形式中。该研究计划将研究将超薄芯片安装到含有图案化导电互连和键合焊盘的柔性聚合物薄膜薄带上的方法。单独的芯片将位于带材上，塑料衬底上的导电轨道将它们聚集在一起，形成一个长的、非常薄的、灵活的电路或灯丝。然后，长丝将被经典的纺织纤维(例如聚酯、棉花、羊毛、丝绸)包围，并连接到导线上，形成电子纱线(EY)，本质上看起来像是标准的纺织纱，但其中嵌入了电路和元件。最终目标是将这些EY结合到纺织品中，以保护电子元件和互连不受严格使用的影响，同时保持纺织品的手感、悬垂性和透气性。这项技术的一个关键方面是使用超薄模具，这种模具具有高度的灵活性，与矩形基准面一起，将使模具在灯丝内的轮廓最小化。这将有助于减少对纱线的影响，使电子设备几乎看不见，并将纱线直径降至最小。
