The continuous miniaturization, increased speed, extended durability, and declining prices of electronic devices have sparked curiosity about the reasons behind these advancements. Two key factors contribute to this phenomenon. Firstly, Moore's Law states that the size of transistors on a chip halves or allows for double the number of transistors every eighteen months to two years, enabling more powerful and compact devices. Secondly, advancements in battery chemistry have led to the development of longer-lasting electronic devices in smaller form factors. However, there are limits to further size reduction, particularly due to the electromechanical nature of certain devices. Human interfaces, such as buttons and displays, present challenges in making devices smaller. To overcome this, remote interaction methods using RF devices, voice recognition like Siri, and even eye movement tracking are emerging, allowing for smaller device sizes without compromising usability.
