We report on the development of inkjet-printed thin-film resistors using both organic and inorganic ink formulations. The passive devices were manufactured on flexible polymer substrates in ambient condition without the need for a cleanroom environment or inert atmosphere and at a maximum temperature of 150 C. By using the same manufacturing process, the rapid electrical sintering (RES) method is demonstrated as effective for the fabrication of inkjet-printed, programmable Write-Once-Read-Many (WORM) memories. Several hundred fully inkjet-printed resistors with different parameters were fabricated and subsequently morphologically and electrically characterized with the aim of obtaining statistically significant data. From a manufacturing process viewpoint, the procedures based on inkjet printing herein described are highly attractive: they do not require high temperatures, low pressures, special atmospheric conditions, and any masks, therefore providing a versatile low-cost approach to fabricate passive electrical components and simple circuits useful for the electronic industry. Printing can be carried out at a sufficiently low temperature to avoid damage to the fabric substrate and these devices can be used in a range of applications requiring flexible and conformal devices from embedded passive filters in PCBs to wearable electronics.

我们报告了使用有机和无机油墨配方开发的喷墨印刷薄膜电阻器的发展情况。无源器件是在环境条件下在柔性聚合物基板上制造的，而无需洁净室环境或惰性气氛，并且最高温度为150C。通过使用相同的制造工艺，快速电烧结（RES）方法被证明是有效的用于制造喷墨打印的可编程一次写入多次读取（WORM）存储器。制造了数百个具有不同参数的全喷墨印刷电阻器，随后对其进行了形态学和电学表征，以期获得具有统计意义的数据。从制造过程的角度来看，此处描述的基于喷墨打印的过程非常有吸引力：它们不需要高温，低压，特殊的大气条件和任何遮罩，因此提供了一种通用的低成本方法来制造无源电子组件和对电子工业有用的简单电路。可以在足够低的温度下进行打印，以避免损坏织物基材，并且这些设备可以用于需要柔性和共形设备的一系列应用中，从PCB中的嵌入式无源滤波器到可穿戴电子设备。
