“…From this figure we see clearly that the sensitivity of sensor can reach 15.8 nm/GPa, the results show that the sensitivity decreases and reaches the lowest value of sensitivity 10.15 nm/GPa. Comparing with other pressure sensor using PhCs which has a sensitivity of about 13.9 nm/GPa under the dynamic range between 0 and 2 GPa [9] our designed sensor has higher sensitivity.…”

In this work, we design a new pressure sensor based on two-dimensional photonic crystal waveguide coupled to a point-defect resonant microcavity. The mechanism of sensing is based on the change of the germanium refractive index as function of the hydrostatic pressure P . The resonant wavelength will shift when pressure variation induces change in the refractive indexes of the structure. The pressure variation causes the shifting of defect modes. The properties of the refractive index sensor are simulated using the finite-difference time-domain algorithm and the plane wave expansion method. These kinds of sensors have many advantages in compactness, high sensitivity, and various choices of materials.

Wearable/flexible electronic sensing systems are considered to be one of the key technologies in the next generation of smart personal electronics. To realize personal portable devices with mobile electronics application, i.e., wearable electronic sensors that can work sustainably and continuously without an external power supply are highly desired. The recent progress and advantages of wearable self-powered electronic sensing systems for mobile or personal attachable health monitoring applications are presented. An overview of various types of wearable electronic sensors, including flexible tactile sensors, wearable image sensor array, biological and chemical sensor, temperature sensors, and multifunctional integrated sensing systems is provided. Self-powered sensing systems with integrated energy units are then discussed, separated as energy harvesting self-powered sensing systems, energy storage integrated sensing systems, and all-in-on integrated sensing systems. Finally, the future perspectives of self-powered sensing systems for wearable electronics are discussed.

“…In 2014, Shanthi et al [21] proposed a 2D PC pressure sensor that consists of two PC quasi waveguides and L3 defect that is placed in between the two quasi waveguides. In 2016, Tao et al [22] proposed a 2D PC pressure sensor that consists of two PC quasi waveguides and an optimized nanocavity that is placed in between the two quasi waveguides. In 2017, Wong et al [23] realized and simulated (using FEM analysis and also rigorous coupled-wave analysis) a pressure sensor using PC mirror pressure-sensing diaphragms with silicon-on-nothing (SON) reference cavities.…”

This paper reports the design and three dimensional (3D) simulation of a new photonic crystal (PC) pressure sensor. The device is constructed using a GaAs-based 2D PC slab on SiO2 substrate. The strain/stress simulations and also the spectral simulations are done using CST Studio Suite. In this investigation, the sensitivity of the proposed pressure sensor is calculated by considering the variation of the refractive index and also the deformation of the structure. The numerical results show that when pressure is applied, the refractive index variations cause an increment in the resonant wavelength of the transmission spectrum, but the deformation factor cause a decrease in the resonant wavelength. It has been shown that the relationship between the applied pressure and the resonant wavelength of the designed micro-cavity is linear. Based on the simulation results, the quality factor of the designed micro-cavity and the sensitivity of the pressure sensor are 2200 and 3.5 nm / GPa, respectively.
