Mr. Vishal Goyal, Senior Manager – Technical Marketing, Analog and MEMS Group, RF, Sensors and Analog Custom Products, India, Asean and ANZ, STMicroelectronics spoke to EM during the recent MEMS media briefing about MEMS product growth, market trends and ST product portfolio. Excerpts from Interview.
1. Explain ST’s portfolio and strategy in MEMS for the diverse markets and applications (such as medical, automotive, industrial, and defense)? What is focus for India?
India is a land of opportunities and it is emerging as a manufacturing hub. Global customers are setting up Design and Manufacturing activities in India. This is open good opportunities for MEMS and sensors in India. We are seeing lots of interest in MEMS, Sensors, and RF amongst customers here. MEMS have seen massive growth in mobile phones. MEMS is also a key pillar in IoT applications. MEMS sensors like Accelerometers and Gyroscopes, as well as Humidity and Temperature sensors are widely used in IoT applications. A few use cases include Home Automation, Smart City, and Smart Industry. Sensor data will also enable a wide range of cloud services .In India, MEMS has wide usage. We are working in the Automotive, Industrial and IoT segments and to expand and develop the MEMS market, we need to emphasize the advantages of MEMS and offer education and training.

B. SensorTile connectable sensor node: plug or solder
Description
STEVAL-STLCS01V1 (SensorTile) is a highlyintegrated reference design that can be pluggedinto form-factor prototypes, adding sensing andconnectivity capabilities to new designs through asmart hub solution. It can also easily supportdevelopment of monitoring and trackingapplications like standalone sensor nodesconnected to iOS™ or Android™ smartphoneapplications.
The SensorTile occupies a very small 13.5 x 13.5mm square outline, with all the electroniccomponents on the top side and a smallconnector on the bottom side to plug it onto thecradle expansion board. The connector pinout isrepeated on 18 PCB pads to render theSensorTile a solderable system on module aswell.
