| 2 | Flexible Integrated Circuits Based on Carbon Nanotubes显示文摘CONSPECTUS:Flexible integrated circuits,working as the core unit of information processing,have been a subject of extensive research;they are essential to realize fully flexible electronic systems,which possess advantages over the current hybrid flexible systems(part or all based on rigid silicon chips)because of their extended application forms,better adaptability,and greater ability to operate at biotic/abiotic interfaces.To a great extent,the deliverable functionality of the ultimate integrated system is determined by the information handling capability of flexible integrated circuits,which is highly dependent on their performance and integration scale.Additionally,as the applications of flexible electronic systems become increasingly favorable in portable,wearable,or remote forms with a restrained power supply,the power dissipation of flexible integrated circuits becomes crucial,as they consume considerable energy in a system.Due to the restricted fabrication circumstances on flexible substrates with a low thermal budget and complex working environments(from the perspectives of both mechanical and electrical conditions),pursuing flexible integrated circuits with high performance,decent integration scale,and low power consumption is very challenging,but it is necessary for advanced,fully flexible systems.Other characteristics,such as biocompatibility,degradability,and configurability,would add value to flexible integrated circuits and introduce unconventional forms and new deliverables for flexible electronics.In this Account,we summarize our efforts toward developing carbon nanotube-based flexible integrated circuits over the past five years.As promising candidates for constructing next-generation chips,carbon nanotube-based integrated circuits have demonstrated their superiority in performance and power consumption,and we extend these advancements to a flexible form through material optimization,device design,processing technology development,etc.We start with a brief introduction to carbon nanotube properties to reveal their intrinsic advantages as channel materials for next-generation electronics.Next,we discuss the manufacturing methods we developed to construct integrated circuits on flexible substrates via a direct fabrication or transfer process to maintain these advantages and fit the circuits to different application circumstances.Then,demonstrations of carbon nanotubebased flexible integrated circuits with different forms and characteristics are presented,including(1)the implantation of complementary metal-oxide-semiconductor circuits on ultrathin substrates with high performance,(2)transferrable integrated circuits with a biointegration capability and low power consumption,(3)degradable integrated circuits manufactured at the wafer scale with a high yield and high uniformity,and(4)configurable integrated circuits with multiple functions.Integrated flexible sensor systems constructed with some of these circuits have also been introduced.Finally,we end the Account with an overview of the remaining challenges and new opportunities that have been opened up for carbon nanotubes in flexible integrated circuits and new forms of electronics. | Youfan Hu Lian-Mao Peng Li Xiang Heng Zhang | 2020 | Accounts of Materials Research2020，1，1： | 2 |
| 4 | Triboelectric nanogenerators with a constant inherent capacitance design显示文摘Triboelectric nanogenerators(TENGs)utilize the phenomena of contact electrification and electrostatic induction to harvest mechanical energy from the environment.A good match between the motion frequency and the circuit characteristic frequency is critical for the effective power generation of a TENG.However,most TENGs have a time-dependent inherent capacitance(TICTENG),which hinders an optimal design for efficient energy conversion.Here,we propose a novel structure of a TENG with a constant inherent capacitance(CIC-TENG)and a mathematical model is established to provide analytical expressions of key output parameters of the device,which gives numerical simulation results that are in good agreement with the experimentally obtained results.Figures of merit and an optimization strategy are also given as guidelines for the optimization of material selection,geometry design,etc.Furthermore,a disk-formed CIC-TENG(DCIC-TENG)with polarity-switched triboelectric pairs is constructed to harvest unidirectional mechanical energy continuously,achieving an output power density of 55 mW/m^(2).The effects of the motion frequency,the number of electrodes and triboelectric pairs on the charge transfer efficiency of the DCICTENG are assessed and a preferred design strategy is given.Finally,the CIC-TENG demonstrates approximately two-fold advantages in power transfer efficiency over the TIC-TENG,and a DCIC-TENG-based self-powered anemometer was fabricated to measure wind speed in real time. | Lanyue Gan Fan Xia Panpan Zhang Xijun Jiang Yuxuan Liu Simiao Niu Youfan Hu | 2023 | Nano Research2023，16，3： | 0 |
