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.

Micro/nanoelectromechanical systems (M/NEMS), especially micro/nanomechanical resonators, provide an unprecedented platform for investigating a wide range of applications in both fundamental physical phenomena (such as quantum‐level problems) and engineering and applied sciences (like sensing physical quantities and signal processing). In sensing context, these tiny resonators are invaluable tools for detecting weak forces and single molecules. Measuring such small variations in sub‐nanometer amplitudes at high frequencies has created many practical challenges. Therefore, maximizing the responsivity to a specified input parameter and minimizing the responsivity to other inputs such as noise are considered as the optimal design for the excellent performance in nanoresonators. The present review aims to summarize some of the recent progress in this rapidly advancing field. Specifically, more attention is paid to the topics related to the dynamical behaviors of micro/nanoresonator and their practical applications. First, the theory behind micro/nanoresonators is described. Then a summary is presented of the basic concepts in resonant devices. In addition, several commonly dynamical techniques to enhance sensitivity are introduced. Finally, the devices are classified based on linear and nonlinear, single and array, symmetric and asymmetric, and frequency shift‐based and amplitude shift‐based resonators, along with the relative advantages and disadvantages of each one in engineering applications.

“…Thus, Jia et al ( 2021) integrated the reverberating nano or micro sensors (gravimetric) towards the biochemical recognition of biomolecules in liquid and air. The gravimetric sensor with immobilized enzymes was proposed to be beneficial towards the detection of trace analytes in bacteria, biomarkers, DNA, volatile organic compounds, chemical vapors, and pollutant gases, via distinct in-plane, torsional, extensional, and flexural modes [59].…”

In recent times, nanomaterials with semiconductor properties are introduced as a potential transducer in biosensors, which can be credited to their intrinsic, elevated surface-to-volume proportion, enhanced sensitivity, and improved surface properties. The surface properties of nanomaterials have made them a significant transducer matrix towards the immobilization of bioreceptors, which eventually enhances the identification threshold and the biosensor sensing capability. Several nanomaterials, such as polymer, metal oxide, metal and carbon-based, as well as nanocomposites, are used towards transducer manufacturing, eventually being incorporated in the biosensors. The current chapter lays an outline with respect to biosensors that are fabricated with nanomaterials as a transducer, where enzymes acting as a bioreceptor, are immobilized on their surface. In addition, the biosensing mechanisms of the enzyme immobilized nanomaterials, their efficiency, detection limit, and sensitivity, are also discussed.
