Graphene remains of great interest in biomedical applications because of biocompatibility. Diseases relating to human senses interfere with life satisfaction and happiness. Therefore, the restoration by artificial organs or sensory devices may bring a bright future by the recovery of senses in patients. In this review, we update the most recent progress in graphene based sensors for mimicking human senses such as artificial retina for image sensors, artificial eardrums, gas sensors, chemical sensors, and tactile sensors. The brain-like processors are discussed based on conventional transistors as well as memristor related neuromorphic computing. The brain−machine interface is introduced for providing a single pathway. Besides, the artificial muscles based on graphene are summarized in the means of actuators in order to react to the physical world. Future opportunities remain for elevating the performances of human-like sensors and their clinical applications.

“…[3,53] Some other recently developed anodes with high tap density and volumetric capacity are also included for comparison. [54][55][56][57] The superior rate performance of FTNO-1000 is expected to be caused by the shortened Li + diffusion channel length as well as the smaller grain size, of which the effect on the specific Li + transfer kinetics within these three electrode materials will be discussed below. The long-term cycling stability of the electrodes was also investigated at 2 and 5 C. Initial 5 cycles are activation of the electrodes and calculation of the capacity retentions presented below are based on the discharge capacities at sixth cycle.…”

Wadsley–Roth phase titanium niobium oxides have received considerable interest as anodes for lithium ion batteries. However, the volume expansion and sluggish ion/electron transport kinetics retard its application in grid scale. Here, fast and durable lithium storage in entropy‐stabilized Fe0.4Ti1.6Nb10O28.8 (FTNO) is enabled by tuning entropy via Fe substitution. By increasing the entropy, a reduction of the calcination temperature to form a phase pure material is achieved, leading to a reduced grain size and, therefore, a shortening of Li+ pathway along the diffusion channels. Furthermore, in situ X‐ray diffraction reveals that the increased entropy leads to the decreased expansion along a–axis, which stabilizes the lithium intercalation channel. Density functional theory modeling indicates the origin to be the more stable FeO bond as compared to TiO bond. As a result, the rate performance is significantly enhanced exhibiting a reversible capacity of 73.7 mAh g−1 at 50 C for FTNO as compared to 37.9 mAh g−1 for its TNO counterpart. Besides, durable cycling is achieved by FTNO, which delivers a discharge capacity of 130.0 mAh g−1 after 6000 cycles at 10 C. Finally, the potential impact for practical application of FTNO anodes has been demonstrated by successfully constructing fast charging and stable LiFePO4‖FTNO full cells.

“…However, traditional LIBs could not meet the ever-increasing energy and safety demands for electric vehicles (EVs) up to now. [1][2][3][4][5] The low insertion/extraction kinetics of the graphite anode restricts the Li-ion diffusion, resulting in a weak rate capability and fast-charging performance. The low working potential (≈0.1 V versus Li + /Li) of graphite is close to lithium plating potential, possibly causing "dead" Li and lithium dendrite growth, which may cause fast capacity decay and serious safety issues.…”

Traditional lithium‐ion batteries cannot meet the ever‐increasing energy demands due to the unsatisfied graphite anode with sluggish electrochemical kinetics. Recently, the perovskite material family as anode attracts growing attention due to their advantages on specific capacity, rate capability, lifetime, and safety. Herein, a double perovskite La2MnNiO6 synthesized by solid‐state reaction method as a high‐performance anode material for LIBs is reported. La2MnNiO6 with an average operating potential of <0.8 V versus Li+/Li exhibits a good rate capability. Besides, the Li|La2MnNiO6 cells perform long cycle life without decay after 1000 cycles at 1C and a high cycling retention of 93% is observed after 3000 cycles at 6C. It reveals that this material maintains stable perovskite structure with cycling. Theoretical calculations further demonstrate the high electronic conductivity, low diffusion energy barrier, and structural stability of the lithiated La2MnNiO6. This study highlights the double perovskite type material as a promising anode for next‐generation batteries.
