Mobile health technology is a rapidly growing field with numerous promises to make substantial impact in our lives. To open this special issue, which brings to you many exciting research results in mobile health technology, we discuss two important aspects of this technology. One is how they can be integrated in our daily lives as important care devices, especially during periods such as the more and more frequent pandemics around the world. Having discussed their advantages, we calculate their estimated footprint in the energy consumption and dioxide carbon they produce globally. With that we raise awareness and invite researchers to work on reducing their energy consumption to ensure that they maintain a low footprint even if their numbers explodes in the near future. We finish this article with a brief teaser of the papers published in this special issue and wish you a good read.

移动健康技术是一个快速发展的领域，有望对我们的生活产生重大影响。本期特刊为您带来了许多令人兴奋的移动健康技术研究成果，为了打开这一特刊，我们将讨论这项技术的两个重要方面。一是如何将它们作为重要的护理设备融入我们的日常生活，尤其是在世界各地流行病越来越频繁的时期。在讨论了它们的优势之后，我们计算了它们在全球产生的能源消耗和二氧化碳中的估计足迹。因此，我们提高了认识并邀请研究人员致力于减少他们的能源消耗，以确保即使他们的数量在不久的将来爆炸式增长，他们也能保持低足迹。
