A. According to Gartner, MEMS-based smart sensors are set to gain maximum traction in the worldwide smart sensor market that is forecast to grow to $57.77 billion by 2022; at 18.1% CAGR. The market is driven by factors including concern toward security & surveillance, rising need for energy-efficient devices, growing consumer electronics sector, surge in automotive industry on a global basis, favorable government initiatives, and growing trend of miniaturization in sensors.

MEMS in India is at its starting point and 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

Q. The IoT is a very big concept which covers a lot of segments. Which segments are ST mainly focused on?

A. Our IoT strategic focus addresses Smart Industry, Smart Home, Smart City and Smart Things. Smart Industry can bring safer and more efficient manufacturing. The philosophy of the Smart City is to share resources better. The Smart Home will improve our quality of life and our security. Smart Things can bring innovative cost-saving solutions for healthcare.

Q. What is your growth perspective for Indian MEMS industry?

A. STMicroelectronics has partnered with many Indian companies and have been working with some of them for two years and now their products are being sold in Europe and USA markets. We hope more and more customers can know MEMS better.

STMicroelectronics globally has huge experience in promotion of MEMS products and we also have had great success in embedded systems. We have developed a kit, development tools and software that help develop embedded systems with MEMS and the full portfolio of ST products. The growth in consumer electronic products alongside the introduction of the sensors in the automotive and medical segments ensures stable growth and the continuing expansion of the MEMS sensors market.

Q. Talk about ST’s latest products displayed

i) SensorTile connectable sensor node: plug or solder

STEVAL-STLCS01V1 (SensorTile) is a highly integrated reference design that can be plugged into form-factor prototypes, adding sensing and connectivity capabilities to new designs through a smart hub solution. It can also easily support development of monitoring and tracking applications like standalone sensor nodes connected to iOS™ or Android™ smartphone applications.

The SensorTile occupies a very small 13.5 x 13.5 mm square outline, with all the electronic components on the top side and a small connector on the bottom side to plug it onto the cradle expansion board. The connector pinout is repeated on 18 PCB pads to render the SensorTile a solderable system on module as well.
