Tape that when the correct note is held at the right frequency for a couple of seconds, will vibrate itself loose.
Make it a note that is rarely heard or else it would come loose every time someone plays the cello. A special tool could produce the note.
Like how a wine glass can shatter.

"Dear Dad, please call me back when you get this note so I can pay you back all that money..." |

I think you will have trouble getting enough energy into the adhesive that way. Adhesive is so elastic that it dissipates energy easily and the damping spreads out any resonance. |
|

What about the reverse? Adhesive that is activated by sound. Ultrasonic energy might be used to stimulate polymerization. I see potential applications in laminates. Where gaps of one wavelength would set up standing harmonic waves. I could see your idea working if the adhesive had, microspheres in it of certain diameter that would resonate and shatter. Thereby reducing the adhesives hold. |

I'm trying to imagine what in the
bejezzus this HRA would be for. i can
picture some rubeberg contraption
involving taping a key to the inside of a
door, so if you come home shitfaced or
lost your key you can slide a paper
under the door, belt out the note and
your spare key will fall down and you
can fetch it to let yourself in. |
|
| |
So if you want sonic key, that is if it's
technically possible to make tape like
that, probably easier to make a lock
that springs open if you hit the right
note. Right? |

What did you want to do with this magic
HRA tape? |

Good show, but don't hang too many pictures in one room with the same note. |

Flight TX245 broke apart at cruising altitude.
Unfortunately the white noise from air turbulence affected the adhesive..... |
|

[Spare parts] that would be sonic welding, which is widely known to exist. |

[DF] Geckos exhibit some of these characteristics - as you all know, geckos, and lots of insect species, use attitudinal control of their foot-pad nano-scale setae and weak molecular attraction forces to 'stick' to surfaces. If you play certain frequencies at a gecko, it spasms, the attitude of the setae changes and it falls off the wall. Best done with a skin flute. |
