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.

“…By endowing different structure colors and FL colors with Arabic numerals, the different loading information of security patterns are obtained by in turn switching pH, temperature, viewing angle, and UV stimulations, and demonstrating it is a sequential identification and decryption strategy for information protection. [115] The change of optical properties of security patterns induced by different external stimuli factors endows the security patterns with different information outputs under various conditions, showing great potential in practical applications. To achieve better performances, the next-generation information security technologies need more convenient and friendly stimuli conditions (such as low-temperature, low humidity, and other low-risk factors) and more faster response speed to these stimuli conditions.…”

the requirements of the market because counterfeiters have very sophisticated techniques to replicate current anticounterfeiting techniques. [2] Thereby, the development of advanced information encryption and anti-counterfeiting strategies that are difficult to replicate is of great significance and has an irreplaceable position in practical application. Based on this background, stimuli-response information encryption and anti-counterfeiting techniques are proposed to achieve high information encryption and anti-counterfeiting strength. Important encoding information is stored and read out in an "on-off" way by altering the stimulation situations. By screening different stimulus conditions, the researchers found that light-induced tunable optical output possesses the advantages of easy operation and promotion, fast detection speed, and low cost, and has great potential in practical applications. [3] It is well-known that optical materials are a typical example, which can be excited by different light sources and then produce controllable optical output. By designing various
