Sensors: What’s in YOUR Smartphone?
In the growing functionality of high end devices, the spread of basic smartphones, and the emergence of new device types – wearables, etc. – sensors are a $60.4B market that is growing at a 9.2% CAGR. We categorize them into 5 groups – physical, optical, radio, electrical and chemical – each serving specific applications and requiring particular design and manufacturing disciplines. As such, competition amongst sensor manufacturers stays within these silos. For sensor functions already well embedded into portable devices, suppliers are challenged to minimize cost, footprint and power draw, often integrating multiple functions of a type into a single solution. Emerging functions, such as gesture control or biometric ID, have drawn approaches using different sensor types, although economics and performance will eventually drive standardization. New devices are a growth market for existing sensor types, but may also create opportunity for new sensor components suited to specific applications. While we are bullish on new portable device opportunities for sensor components, we note that many longstanding sensor products are commoditized, particularly within well established traditional end markets, such as automotive and industrial automation.
