Embedded M2M module
NEC showed off an embedded M2M module to connect the real world and the cloud. Using a vibration energy harvesting device, the M2M module needs no power source to turn on the switch. The photo shows a pair of shoes embedded with a vibration energy harvesting device (shown front). When, for example, a senior citizen living alone wears the shoes and walks around, the shoes automatically lets a caregiver know where he is via a smartphone.
