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.

“…An antenna's design varies based on specific applications, and often involves coating techniques to tailor it for particular purposes. For instance, Mahdi et al [10] employed a graphene-coated dielectric resonator antenna (DRA) to investigate human retinal photoreceptors, showcasing its suitability to the vision spectrum. In another approach, Moghadasi et al [11] utilized a graphene-coated nano-aperture biosensor, achieving dualband characteristics and enhanced electric field enhancement, enhancing sensitivity.…”

Hepatocellular carcinoma (HC) is a common liver cancer often associated with chronic liver diseases such as hepatitis B and C-induced cirrhosis. Multiple treatments are available, including microwave ablation (MWA), which has proven effective. This is attributed to its proved ability to eliminate liver tumors with a successful rate of more than 85%. However, in order to maintain healthy tissues and establish good ablation practicability, the temperature involved should be controlled. This can be achieved by monitoring different parameters including thermal conductivity, heat capacity, and blood perfusion. For this purpose, an antenna probe is usually employed to localize heat distributions and identify heating efficiency. Many types and shapes of antenna probes for MWA have been reported in different studies. Thus, in the current study, a numerical model is established to investigate the performance of the antenna based on its shape. A finite element model (FEM) was developed to examine the specific absorption rate (SAR), distribution of temperature, and coefficient of reflection. Closed and conventional single-slot antennas were targeted via this model. The antenna was then designed to have a reflection coefficient lower than 10 dB and heating of a spherical shape profile. The findings of the study can aid in determining the optimal parameters required for the highest effectiveness of MWA in the treatment of HC at early stages with the lowest amount of invasiveness and collateral harm.
