It is reasonably easy to see where the direct demand is across a broad set of sensor types and diverse set of applications including asset-tracking systems, smart grids and building automation,
However the bigger demand is indirect which IHS puts down to the use of MEMS in probe cards, used to test the memories that go into data centers to support industrial IoT and in optical cross-connect switches (OXCs) used to link server racks in data centers.
Figure 1 shows the direct and indirect annual demand for MEMS components in industrial IoT. The MEMS used in direct applications are the usual suspects: are pressure sensors, inertial sensors, energy scavangers, gas and chemical sensors, timing devices, microphones and scanning mirrors.

The worldwide annual market revenue for MEMS components used directly in industrial IoT equipment will go from $15.6 million in 2013 to about $19 million in 2014 and then climb again to about $30 million in 2015. Over the period 2013 to 2018 IHS is forecasting a compound annual growth rate of 50 percent to take the annual market from $16 million in 2013 to about $120 million in 2018.
