Sensors in Mobile Devices

First wave: MEMS sensors and touch panels (2002 – 2012)

•  Silicon accelerometers became available based on mass production processes for automotive industry; smaller package, lower supply voltages, less power

•  Capacitive touch sensors as a mass volume enabler of mobile device user interfaces

•  Key drivers: adaptive user interface, touch displays, application development

Smart sensor modules and sensor fusion for consumer products (2013 – )

•  Integration of MEMS sensors into smart sensor modules (inertial combos with signal processing and embedded algorithms)

•  Basic motion and gesture recognition algorithms as an integral part of smart sensors •  Key drivers: contextual intelligence, adaptive UI, application specific devices

New materials and intelligent algorithms enable more sensing (2015 – )

•  New materials, such as graphene, enable arrays of chemical and environmental sensors with high level of integration (energy, sensors, analog electronics)

•  Machine learning methods enable intelligent, adaptive, learning, predictive sensors

Technology Differentiation and

Disruptions in Manufacturing

Europe can compete by radically

differentiating technologies –

Europe can’t compete by minimizing costs

of traditional technologies.

Europe can compete by providing truly

disruptive manufacturing solutions –

not by incremental development steps for

existing manufacturing capabilities.
