可靠、非永久性的连接器是电子纺织设备开发中的一个重大挑战，需要增加它们的模块化，这是它们能够被修复或回收的关键因素。弹簧加载触点和磁性紧固件的组合是一个很有前途的选择，因为这些组件具有在柔性设备中使用所需的小尺寸和机械柔顺性。这封信详细介绍了对由两对1毫米厚的NdFeB纽扣磁铁固定的五针弹簧手指连接器的评估。连接器经过9厘米直径的弯曲和拉直，以分析其是否适合在电子纺织设备中使用。结果表明，采用1.3 mm的高弹簧，支座的抗弯刚度为1.16美元，10-4 Nm2倍的抗弯刚度，在该试验中可以达到100%的可靠性。这些结果表明，有必要使用容易压平的小弹簧。然而，它们的工作范围很小，这意味着它们在连接到不平坦的表面时可能不那么可靠。
Reliable, impermanent connectors are a significant challenge in the development of e-textile devices, needed to increase their modularity, a key factor in their ability to be repaired or recycled. The combination of spring loaded contacts and magnetic fastenings is a promising option, as these components exhibit the small size and mechanical compliance necessary for use in flexible devices. This letter details the evaluation of a five-pin, spring finger connector held in place by two pairs of 1-mm-thick NdFeB button magnets. The connector is subjected to bending and straightening around a 9-cm diameter to analyze its suitability for use in an e-textile device. The results show that with 1.3-mm high springs and a backing with a flexural rigidity of $1.16\,\, {}\times {}10^{-4}$ Nm2, 100% reliability can be achieved on that test. These results indicate a necessity to use small springs that can easily be flattened. However, their small working range means that they may not be as reliable when connecting to uneven surfaces.
