[NewCandle] AdaptivEnergy Module

[John Steck]

Not sure if the graph attached to this email will make it through the NewCandle rebroadcast, but thought I would give it a try.  In brief, the output function for this device is reported to be: 

y= 0.6015x^2 + 11.571x 

y= Power (mW) 
x= Acceleration (g)

John, 

 

The kits are $699.00

Please see the link below and here is more information about our technology. The beam is 60Hz in the demo kit but can be customized based on frequency data. If you are open we can discuss your potential applications.

 

This is the power output versus acceleration for our latest EH beam.  This is the beam that will be in the development kits.The power output of a piezoelectric energy harvesting beam increases quadratically with acceleration.  This is shown in the plot by the excellent curve fit to the data.  The equation for the trendline can be used to interpolate to power output between data points.  As you can see the power output follows a nice quadratic trend to zero at low Gs.  For example, the power output at 0.1 G is 1.2 mW and at 0.05 G is 0.58 mW.  0.05 G is an extremely small vibration amplitude.  This would be barely perceptible to human touch (The threshold of human vibration perception is 10 mG's at 100 Hz).  We have wireless sensing demo setup now that will transmit data every 16 seconds with a 40 mG input at 60 Hz.
