Basic elements
1. Identification purposes
The basic idea is that combinations of resonance frequencies may be used for identification purposes. Each ID chip is designed or “tuned” for a certain combination. Given a possible spectre of resonance frequencies and the number of actual resonances on each chip the total number of combinations or IDs may be calculated for a series of chips.
The combined signal and reading system must be able to effectively transfer acoustic energy to the passive chip in order to make all the resonators return proper signals at right pitch and with sufficient strength.

2. CR-Controlled Release

The resonance principle may also be used in order to make a membrane burst, enabling the release of the content in a chamber behind.

 
Miniaturization – for fish and the biotech industry
In order to qualify for the biotech industry the chip may be miniaturized. At the same time the signal frequency will increase. However, if the reading distance is also reduced this can be a viable scenario.

The last generation chip tag for fish measures 1,5 x 1,5 x 0,4 mm3. Resonators 7+1 (reference) along the edge

 

Renewable energy storage and distribution

Direct conversion of renewable energy to electric power limits the ability to serve the market properly. Energy has to be stored and converted to electricity exactly when needed.

The WaveGas innovations shall mainly contribute to solve this problem. But there are other great opportunities; biogas compression is one. See Projects.

 

The picture below shows the 2-step compressor  lab prototype which was tested successfully at NMBU (The University at Aas).
