Nanosensors for smartphone sensing method

Technological advances in smartphone have permitted a superior multiplicity for communications of devices with one other restraining human interference. A significant improvement in integration of nanosensors in smartphones for disaster management, public health emergencies, and in the aftermath of life-threatening disorderly events is needed. Since nanosensors are very sensitive towards pressure, we anticipate that the advancement of this technology will add a significant value to vulnerable countries and possibly decrease the number of deaths. Thus, in this chapter, we deliberated manners of improving the self-sufficient energy production and use in smartphones, based on current and promptly evolving technologies. Besides, enhancements in physical toughness and offline operability are also discussed. The growth of smartphone technology up to now is not equivalent, either throughout the countries or within them. Fundamentally, smartphone technology across the emerging countries is very limited, worse most of these emerging countries still experience significant number of earthquakes, leading to higher number of deaths and ultimately unending poverty and hunger.
