This paper is devoted to the presentation of a quantitative analysis of the Junctionless Gate All Around RADFET (JL GAA RADFET) dosimeter, where the numerical simulation has been carried out using the Atlas 3‐D simulator. The impact of the total dose, alternative gate materials and the channel doping on the threshold voltage of the JL GAA RADFET is addressed. The obtained results have indicated a significant improvement in the subthreshold parameters when compared to the conventional GAA RADFET dosimeter. Therefore, the implementation of junctionless‐based sensors in the near future can provide more accurate results with low costs, in addition to alleviating many difficulties in the measurement procedure.

“…Recently, the Ion Sensitive FETs (ISFETs) sensors attract much attention in reliable and high performance applications for engineering and medical applications due to their reliability, low power consumption, non-destructive read-out of chemical and electrical information, high molecule detection range, and compatibility to standard CMOS technology [1][2][3][4][5][6]. However, with the progression of microelectronic industry and the increasing of the sensor performances, control of parasitic parameters and improvement of the sensor reliability against the biological and chemical variation of the neutral molecules are the biggest challenges in future embedded electronic systems for sensing and monitoring applications.…”

In this chapter, an analytical analysis of a new graphene-based sensor called Dielectric Modulated Graphene Field Effect Transistor (DMG-FET), for high-performance biomolecule sensing applications, is developed and established by experimental validation. The challenges to develop analytical and compact models to investigate the graphene-based devices for biomolecule sensing applications are presented in this chapter. In this context, analytical expressions of the subthreshold drain current through the use of a good approximation is illustrated, and the sensitivity of conventional FETbased sensors is improved. An analytical analysis comprising biomolecule concentration effect, drain current, threshold voltage shift and sensitivity behavior for DMG-FET are developed, in which the drift-diffusion transport mechanism is used to get accurate analytical models for investigating the DMG-FET behavior. The sensitivity of the proposed design is compared with that of conventional FET-based sensors. Due to the high performance provided by the proposed sensor, the read of the biomolecule concentrations is carried out by using an appropriate Read-out Circuit, which is suitable for practical low power applications. It is to note that the proposed sensor has better electrical and scaling performance in comparison with the conventional design. This result makes the proposed design as a promising candidate to serve as a highly sensitive low-power and reliable graphene-based sensing applications. For that reason, the dielectric-modulated Graphene FET (DMGFET) provides a practical approach towards biomolecule detection that could be extended to other applications.

Swimming microrobots have been broadly considered and drawn great attention for the mainly recent years, in robotics and biomedical domains, due to their alternative applications. This work models and optimizes a new swimming microrobot design for biomedical applications. The key idea behind this contribution is to find out the best dimension and electromechanical parameters of the investigated swimming microrobot that will yield the maximum thrust force for reliable swimming microrobot applications. The analytical models are developed to calculate the thrust force generated by a hybrid tail. The microrobot is modulated using a nonlinear model-based approach for magnetical control. We show that our proposed device can be significantly improved by using the IPCM hybrid tails with thick link at the end of the tail. Furthermore, the artificial bee colony algorithm is used to ameliorate both, electromechanical parameters and the microrobot geometrical aspect, in order to enhance the performance and robustness behavior of the investigated microrobot. In this context, thrust force of the investigated structure is examined and compared with the conventional microrobots. The obtained results demonstrate that the proposed design can be considered as a potential candidate for high performance microrobot-based applications.
