yes just broadcast the energy amplitude and frequency or monitor on sensor, anyway this signal alone could trigger a physical inspection of the bridge as it could be monitored for changes to its steady state over time.
IR losses stop this size reduction, also the step up ratio needs the wire length.
But it could be broken up into smaller components for highth reduction for example at the cost of adding extra componnets
most aplications will have a well defined vibration frequency but many will not.
Why not design the mems so that the respond to a broader range of frequencie so as to have higher probability of energy being in the pass band of the converter?
Thus harmonics and/or subharmonic frequency components along with the fundametals would most alway fall into the passband.
How do garentee orentaition?
Are the mems designed to except vibration in any direction or do they need to be "inplane"?
That is are the MEMS 3D?
Rule to live by...Don't get sick, and apparently don't be near anyone that is if they have that technology implanted.
Like all technologies, they can be used for good or evil and unfortunately the scale tends to tip towards evil far more today than ever before.
Note that a vibration sensor is a form of microphone. Note that in medical applications, we now face a future in which microphones are implanted into us. Note that the device can report wirelessly. Note the funding source, DARPA. Read the article on MondoNet (go to the home page for it) being developed as a distributed, wireless access fabric that will cover the world. (Note that the developers are concerned with "privacy".) So, let's see: everywhere you go, the government will be able to hear you. O brave new world!
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
