Flexible integrated circuits (ICs), working as the core unit of information processing, are essential to realize fully flexible electronic systems. Due to the restricted fabrication circumstances on flexible substrates, pursuing flexible ICs with high performance, decent integration scale and low power consumption is very challenging. In this talk, I will introduce our recent advances in developing carbon nanotube-based flexible ICs and integrated smart sensor systems. First, I will show that how we can maintain the advantages of CNT-based ICs from a rigid form to a flexible form via properly developed fabrication technology and device design. Then, demonstrations of carbon nanotube-based flexible ICs with different forms and characteristics are introduced, including ultraflexible high-performance complementary metal-oxide-semiconductor (CMOS) ICs, low-power ICs for working on biological surfaces, degradable ICs for eco-friendly applications, and configurable ICs with multiple functions. Integrated flexible sensor systems constructed with these circuits have also been introduced. These results show that enabling powerful flexible ICs to construct fully flexible integrated systems will unlock the true power of flexible electronics, which could provide breakthroughs in various application areas, such as advanced forms of monitoring, diagnosis and therapy.
柔性集成电路作为信息处理的核心单元，是实现全柔性电子系统的关键。由于柔性衬底的制造环境限制，实现高性能、高集成度、低功耗的柔性集成电路非常具有挑战性。在本次报告中，我将介绍我们在开发基于碳纳米管的柔性集成电路和集成智能传感器系统方面的最新进展。首先，我将展示我们如何通过适当的加工技术和器件设计将碳纳米管基集成电路在刚性衬底上表现出来的性能优势保持到柔性衬底上。然后，我将介绍我们所实现的具有不同形式和特性的碳纳米管基柔性集成电路，包括超柔性高性能CMOS集成电路、用于生物体表面工作的低功耗集成电路、用于环保应用的可降解集成电路、具有多种功能的可配置集成电路，以及用这些电路构成的柔性集成传感系统。这些结果表明，实现功能强大的柔性集成电路，构建完全柔性的集成系统，将释放出柔性电子的真正力量，这将为各种应用领域提供新的突破，例如先进的监测、诊断和治疗形式。
