See my fly vest has a pressure valve if there is a change in pressure like hitting water it blows itself up. Sort of like a car air bag. I wonder if the manufacturers have considered that technology as viable. But remote sensors sound pretty cool.

Isn't it nice when someone says "that's a great piece of kit, where did you buy that", then you can modestly reply "you can't buy it, I made it myself". The moral is, it's amazing what you can achieve if you put your mind to it.

The conditions that happen when an avalanche lets loose are so chaotic that I think a pressure change sensor would be hard to do.
Sometimes you are on a slab that starts moving. (Vast majority of avalanches are triggered by the person themselves) To the airbag sensor this is nothing different than normal skiing, but you need to trigger RIGHT AWAY...
Sometimes you get hit from above by an avalanche that is already moving (much less frequent)
Also a G-force/kinetic sensor would not be so great because skiers are often jumping down cliffs and such and subject to pretty heavy shocks.
Pressure does not build up until it is too late. The snow moves like wet concrete and you end up sinking into it. Then it sets like concrete and you have 10-15 mins to live. Hopefully your buddies are able to get down to you, switch on their beacons, find you, dig you out from under 1-2 TONS of snow. All in 10-15mins.
Yak. It just doesn't bear thinking about.

No it's more like an air bladder if the bladder is compressed in any way it triggers the gas to fill it up. They use it on oil Riggs for life jackets ect.

We learned it in school here as well. And I received a lot of training on it in the army. I was in right after the Vassdal avalanche that killed half a platoon, 16 soldiers on excercise. They where ordered into an unsafe valley...and taken by an avalanche...
if it was safe to enter an area, and could refuse, with no consequenses...
But the only kit we had was spades for digging snow profile trenches, and a 5 meter rope to tie around your waste to help find you if you where caught in an avalanche.
But that was back in 1989. Things have changed since then.
Victory awaits the one, that has everything in order - luck we call it
Defeat is an absolute consequense for the one that have neglected to do the necessary preparations - bad luck we call it

Haha - Yes. I skied with a 30 meter cord with big red inflated ball dragging behind me....
Yikes.

Well, well, as I was loading the 3 year old into the car at his daycare, wich also is a good place to park for people going into my hills, there was a man there off loading mountain skis, and back pack, obviously heading up into the hills.
I said hi, and asked him if he knew the conditions up there.
Do you mean the weather he asked.
So I tell him about the avalanche conditions...we are stll at level 4. Right now we have beutiful sunshine, wit a nice layer of powder, but on top of a very unstable hard layer...
He says not to worry, he has all the kit. And goes on to show it to me, and give me a lecture on how experienced he is...fine. It's up to him...I excuse myself and let him go on with his business...
As I walk back to the car, we hear the rumble of an avalanche up in the hils, and see i snow cloud near the top, where he planned to go up and ski from...
...the man looks at it, and throws his pack back into the car, and drives off...

I grew up in Africa and it was drilled into you that if you go into the bush you are on your own, if you get in trouble you have to get yourself out of trouble. You soon learnt think before you acted. Even driving in Africa you can be 2-300 miles from the nearest help. People in this country seem to think that if they get into trouble some hero will come and save them and that's why some of them die!! Lack of self reliance.
