Hmm thanks Borek, gallium oxide sounds promising. I'll do a bit of research into this.

thanks for all the input guys! Is very helpful - hopefully edging closer to a solution.

This is something I had thought about too, but would require a bit of a redesign of the product to fit in the extra components. Its not out of the question, but I'd like to exhaust the options of solely using the conductive liquid first.

Although it may be slightly limiting, using the conductive liquids is a key characteristic of the project, so I'd like to persevere as much as I can. The health risks of the likes of mercury are considerations, and I'm trying to avoid using it at all costs. The liquid will be fully and...

Yeh just need to get my hands on some to experiment. I found that the last conductive ink I used required the glass to be coated with a hydrophobic solution too - but his was just an off the shelf solution. Not sure if it would work with galinstan, but only one way to find out I suppose.

This is a good idea - and might work even with carbon nanoparticles to keep cost down. In the original design, the conductive ink was submerged in oil (baby oil!) to help it flow smoothly. Some form of resin might work with the oil?

the system works in the same way old mercury tilt switches did, but scaled up and using mains voltage. A small tilt switch and relay could be used, but the whole point of the design was to be able to see the elegance of the liquid joining the contacts.

Really hoping someone can help here! Im a product designer, not a chemist/physicist so apologies in advance for any stupid questions. I'm developing a new table lamp which is turned on and off by tilting it. For prototypes I have used a http://www.bareconductive.com/liquidity but this isn't...
