Superconducting travelling-wave parametric amplifiers are promising devices for the near-quantum-limited broadband amplification of microwave signals and are essential for high-quantum-efficiency microwave read-out lines. Built-in isolation, as well as gain, could address their primary limitation: a lack of true directionality due to the potential backward travel of electromagnetic radiation to their input port. Here we report a travelling-wave parametric amplifier isolator that is based on Josephson junctions. The approach uses third-order nonlinearity for amplification and second-order nonlinearity for the frequency upconversion of backward-propagating modes to provide reverse isolation. These parametric processes, enhanced by a phase-matching mechanism, exhibit gain of up to 20 dB and reverse isolation of up to 30 dB over a static 3-dB bandwidth greater than 500 MHz and maintain near-quantum-limited added noise. A Josephson-junction-based travelling-wave parametric amplifier isolator can provide gain of up to 20 dB and reverse isolation of up to 30 dB over a static 3-dB bandwidth greater than 500 MHz and maintain a near-quantum-limited added noise.
超导行波参量放大器是近量子限制的微波信号宽带放大器件,是高量子效率微波读出线路的关键器件。内置隔离和增益可以解决它们的主要限制:由于电磁辐射可能向后传播到它们的输入端口而缺乏真正的方向性。本文报道了一种基于约瑟夫森结的行波参量放大器隔离器。该方法利用三阶非线性放大和二阶非线性上变频的反向传播模式,以提供反向隔离。这些参数化过程,通过相位匹配机制增强,在大于500 MHz的静态3-dB带宽上表现出高达20 dB的增益和高达30 dB的反向隔离,并保持近量子限制的附加噪声。基于约瑟夫森结的行波参数化放大器隔离器可以在大于500mhz的静态3db带宽上提供高达20db的增益和高达30db的反向隔离,并保持近量子限制的附加噪声。

The three-dimensional printing of thermoset materials is of use in the development of flexible electronics and soft robotics. However, the process typically involves the deposition and removal of supporting materials that require extensive cycles of pre- and post-processing. Here we describe a three-dimensional printing method for constructing functional and arbitrary free-standing thermoset structures without using supporting materials. The approach integrates in situ laser-induced solidification with direct ink writing. During printing, the integrated laser is focused on a micro-sized polymer jet, leading to thermoset crosslinking in less than 0.25 s through a strong photothermal effect. The process offers a resolution as fine as 50 μm, with mechanical properties tunable by up to tenfold and electrical properties by up to 20-fold. We used this approach to print stretchable electronics with stiffness gradients for strain inhibition, flexible sensors with high sensitivity and three-dimensional soft magnetic robots for actuation functions. A three-dimensional printing method that integrates in situ laser-induced solidification with direct ink writing can be used to create stretchable electronics with stiffness gradients, flexible pressure sensors with high sensitivity and soft magnetic robots for actuation functions.
热固性材料的三维打印在柔性电子和软机器人的发展中有着重要的应用。然而,该过程通常涉及沉积和去除支持材料,需要大量的预处理和后处理周期。在这里,我们描述了一种三维打印方法,用于构建功能和任意独立式热固性结构,而不使用支撑材料。该方法将原位激光诱导凝固与直接墨水书写相结合。在打印过程中,集成激光聚焦在微尺寸的聚合物射流上,通过强烈的光热效应,在不到0.25 s的时间内实现热固性交联。该工艺的分辨率可达50 μm,机械性能可调10倍,电气性能可调20倍。我们使用这种方法来打印具有刚度梯度的可拉伸电子器件,用于应变抑制,具有高灵敏度的柔性传感器和用于驱动功能的三维软磁机器人。一种将原位激光诱导凝固与直接墨水书写相结合的三维打印方法,可用于制造具有刚度梯度的可拉伸电子产品、具有高灵敏度的柔性压力传感器和具有驱动功能的软磁机器人。

The long-term recording of neural activity could be used to understand complex behaviours and disorders. However, the development of technology capable of such measurements faces a variety of technical challenges, including the relative motion between recording electrodes and tissue and the excessive displaced volume from implanted electronics. Here we report a subnanolitre-volume tetherless optoelectronic microsystem for neural recording. The system relies on light for photovoltaic power and data transfer, through a light-emitting diode, eliminating the need for wires or other tethers. It uses a single AlGaAs diode as both photovoltaic and light-emitting diode. Complementary metal–oxide–semiconductor circuits provide low-noise amplification, pulse-position-modulated encoding and electro-optical transduction. Two-dimensional materials processing techniques, vacuum annealing and atomic layer deposition, in conjunction with a standard complementary metal–oxide–semiconductor fabrication process, provide compact encapsulation against the corrosive conditions of biological media. We show that the subnanolitre neural implant is capable of chronic (365 days) in vivo recordings in awake mice. A neural implant with a subnanolitre-volume can provide year-long in vivo recordings in awake mice.

A self-controlled reconfigurable intelligent surface inspired by optical holography 一种受光学全息术启发的自我控制可重构智能表面

Reconfigurable intelligent surfaces operating at microwave frequencies are of potential use in the development of the sixth generation of wireless communications technology. Such surfaces could, in particular, be used to reprogram the wireless propagation channels in controlled ways and thus provide low-cost wireless capacity boosting, coverage extension and enhanced energy efficiency. To reprogram the channel, each meta-atom of the reconfigurable intelligent surface needs to receive an external control signal, which is usually generated by a base station. However, this requires complicated control cables, which restricts wide deployment. Here we report a self-controlled reconfigurable intelligent surface that is inspired by optical holography. Each meta-atom of the reconfigurable intelligent surface is integrated with a power detector that can record a hologram created from simultaneous microwave illumination from the base station and the user. We use classical Fourier transform to process the measured hologram and retrieve the angular position of the user, which is required for beamforming. As a result, the approach can provide autonomous reconfigurable intelligent surface beamforming without control cables. By integrating power detectors into each of its meta-atoms, a reconfigurable intelligent surface can autonomously determine the location of a user from a microwave hologram formed by illumination from a base station and the user.
在微波频率下工作的可重构智能表面在第六代无线通信技术的发展中具有潜在的用途。特别是,这种表面可以用于以可控的方式重新编程无线传播信道,从而提供低成本的无线容量增加,覆盖范围扩大和提高能源效率。为了对通道进行重新编程,可重构智能表面的每个元原子需要接收外部控制信号,该信号通常由基站产生。然而,这需要复杂的控制电缆,这限制了广泛部署。在这里,我们报告了一种受光学全息启发的自我控制可重构智能表面。可重构智能表面的每个元原子都集成了一个功率探测器,该探测器可以记录来自基站和用户同时微波照射产生的全息图。我们使用经典的傅立叶变换对测量的全息图进行处理,检索出波束形成所需的用户的角度位置。因此,该方法可以在没有控制电缆的情况下提供自主可重构的智能表面波束形成。通过将功率探测器集成到每个元原子中,可重构的智能表面可以根据基站和用户照明形成的微波全息图自主确定用户的位置。

Soft electronic fibres are potential building blocks for a variety of emerging technologies including smart textiles and wearable health monitors. However, it remains a challenge to fabricate fibres that combine conductive and dielectric domains in complex architectures in a simple and scalable way. Here we show that a thermal drawing approach can be used to fabricate stretchable fibre-based sensors from liquid-metal-embedded elastomers. The material formulation and processing parameters can be controlled to create high aspect-ratio stretchable fibres that integrate high-conductivity (around 103 S cm−1) and high-dielectric ( $$kappa approx 13.5$$ ) domains across the fibre cross-section. We illustrate the versatility of our approach by creating an all-liquid-metal-based capacitive fibre sensor, which offers a gauge factor of 0.96, stretchability of 925% and high stability to cyclic deformation.

软电子纤维是各种新兴技术的潜在基石,包括智能纺织品和可穿戴健康监测器。然而,在复杂的结构中以简单和可扩展的方式制造结合导电和介电畴的纤维仍然是一个挑战。在这里,我们展示了一种热拉伸方法可以用来制造基于液体金属嵌入弹性体的可拉伸纤维传感器。可以控制材料配方和加工参数,以创建高纵横比的可拉伸纤维,该纤维在纤维截面上集成了高导电性(约103 S cm−1)和高介电($$kappa approx 13.5$$)域。我们通过创建全液体金属电容式光纤传感器来说明我们方法的多功能性,该传感器的测量系数为0.96,拉伸性为925% and high stability to cyclic deformation. We also integrate our fibre-based sensor into textiles and demonstrate an efficient smart knee brace. A thermal drawing method can be used to create stretchable electronic fibres from a liquid-metal-embedded elastomer that can contain conductive and insulating domains across the fibre cross-section.

However, it remains a challenge to fabricate fibres that combine conductive and dielectric domains in complex architectures in a simple and scalable way. Here we show that a thermal drawing approach can be used to fabricate stretchable fibre-based sensors from liquid-metal-embedded elastomers. The material formulation and processing parameters can be controlled to create high aspect-ratio stretchable fibres that integrate high-conductivity (around 103 S cm−1) and high-dielectric ( $$kappa approx 13.5$$ ) domains across the fibre cross-section. We illustrate the versatility of our approach by creating an all-liquid-metal-based capacitive fibre sensor, which offers a gauge factor of 0.96, stretchability of 925% and high stability to cyclic deformation. We also integrate our fibre-based sensor into textiles and demonstrate an efficient smart knee brace.
