Guest Editorial Special Issue on Circuits and Systems for the Internet of Things—From Sensing to Sensemaking

The Internet of Things (IoT) refers to the interconnection of everyday objects endowed with sensing, processing, communication and energy management capabilities [item 1) in the Appendix] (the “IoT nodes”). Being at the beginning of its “S curve” in terms of stage of adoption [item 2) in the Appendix] (see “innovators” inFig. 1), the IoT promises to be the next big wave that will further raise the technological and economic impact of the semiconductor industry. More than a decade from now, the massive adoption of IoT technologies (see “late majority” inFig. 1) is expected to expand the number of connected devices per person to the order of a thousand, thus reaching an unprecedented scale of trillions of connected devices [item 3) in the Appendix].
