I ran across some phosphor bronze metal alloy strip coils recently and
naturally the thought of
using such in a seismometer comes to mind.  One size is .007" thick X .375"
width,
and the other is .014" thick X 1" width.  The springs are tempered.

The internet yields very little or no recommendations or any real strong
negative
(metal creep..PSN email @ ~1999).

Besides the possible usual flexure use: I do envision (muse) on the thought
of
trying such as a taut vertical strip spring and with a
attached/extended light weight mass
which operates in a horizontal sensing configuration.  Yes; its a old idea
similar to the old
Wood-Andersons of yesteryear; but different only in it being a strip and not
a round
wire as a torsion pivot.

Thoughts?  Recommendations?

Take care, Meredith Lamb
