手機、平板電腦等行動裝置已成為一種普及性極高的電子隨身工具，其方便使用與上網的特性，更讓使用者能隨時分享數位資訊。行動裝置通常內建許多不同的感測器，如影像感測裝置、電子機械式之微機電感測器等。透過撰寫行動裝置之應用程式 (App) 與擴充外接式的感測模組，並結合行動裝置內建多種不同的感測器，則能實現不同儀器上的應用，並成為可攜式的量測裝置。由於行動裝置極為普及，使得以行動裝置為基礎之量測儀器成為一種新興應用產業。在本文中，以行動裝置為開發平台，提出多種不同之生活量測與監控等相關應用。

Mobile devices, such as smart phones and tablets have become widely popular as an access to the internet and an
easier approach to deal with and share real-time digital information. Mobile devices are in general consisted of
the integral design and fabrication of optical, electronic, mechanical and MEMS sensors. Expanding the utilities
of such sensors to perform easier instrumentation and measurement can be achieved by adding internal programs,
commonly known as applications or apps in the device or additional external sensing facilities. The prevalence
of mobile devices lately has made it an emerging yet indispensable fraction and has created a strong niche for the
future of instrumentation and measurement. In this paper, we investigate several examples of how mobile devices
perform measurement and monitoring in real life situations.
