Murata has a very strong expertise in the design and production of analog components, it will be a very good use of this expertise in the design and development of MEMS. This will be a very good step for quality analog components.
Murata is well known for its portfolio of passive product offerings. This is a very good strategic move made by Murata for its growth as MEMS is one of the next big things in the automotive and medical electronics.
"One reason is the energy crisis in Japan. We have shut down all the nuclear plants. And in China the demand for electricity is increasing very rapidly and they face environmental issues." - Why IoT is related to high demand for electricity and environmental issues?
Is not exactly IoT but wireless sensor networks. These will enable the wireless control and sensing of energy consumption and will allow to save energy by turning of lights or heating or air conditioning when not required.
Seems like the early adopters are the ones who don't really care much about the energy bill (at least in the US!) but like the aspect of controlling everything from where ever they are. I know of many friends who ponied up couple of grand $$ for these so they could show off turning the alarm on from their iPhone!
There are already many players in the emerging IoT market, from sensor makers to communication component supplier to solution providers. What is lacking is product that makes sense of sensor data and provides actionable analytics to the users in a familiar form.
