You may recall my previous idea of Sptangdex which went
into very little detail as to how it worked. Further thought
on the matter has led to more details on this. And yes, it's
potentially pervy still, but it also has genuinely non-sexual
applications, including medical ones, and as we all
sexual desire is an engine for technological progress.
This is a smart textile based on much bigger than
nanotechnology. It's based on a fibre which is able to
alternate between locking itself in position and moving
itself over a wide range of angles in three dimensions. The
fibre consists of segmented units each able to respond to a
signal which will instruct them to adopt one of four states,
along with intermediate conditions. These are: passive
(behave like an ordinary textile); mimic (copy the positions
of the adjacent fibres); locked (adopt a specific
orientation and maintain it) and active (move to a specific
three dimensional orientation). There are states between
these extremes. The entire fibre is coated in an elastane
layer. Each unit can be programmed individually and
corresponds to a specific address on the fibre. When
woven together the fibres add a segment address according
to their position in the cloth. It can be controlled by being
addressed with an electromagnetic signal comprising the
number of the fibre unit in the garment, with the segment
address, and the state it is to adopt: passive, mimic,
locked or active. Each of these is also given a number
representing the tendency to be in a particular state and
locked and active state instructions take two further
arguments indicating the angle. These are similar to CPU
opcodes, with passive as binary 00, mimic as 01, locked as
10 and active as 11. These opcodes are followed by two
eight bit values describing the latitude and longitude of
the next unit in terms of a ball and socket joint between
the links. They can also return their angular even if
When woven into a garment with conventional textile used
for the weft, the smart fibres constitute an address space
of around 400 megalocations, each of which can both store
and recall its current state. This can be used to correct
posture and train the wearer in movement, and the
resistance also allows the wearer to increase muscle
strength and enables it to be used as a splint. However,
the garment can also be hacked to control the clothing and
therefore also the wearer (which is the pervy bit but
security measures could make it less hackable). Each unit
only responds if it receives its address - they are called by
name, as it were, meaning that some parts of a sheet are
active and others passive.
This has a number of uses. The passive return of
information gives detailed data on the posture and position
of the wearer. An elderly or infirm person who has been in
the same position for a long time can have an alarm to
alert emergency services. Pressure sores and compartment
syndrome caused by casts can be prevented. Posture can
be improved. Dancing, aerobics, Tai Chi, Yoga, Pilates and
other movements can be taught through muscle memory.
There is a remote control and sensor involved which can
read data on posture and movement and aid that
movement through something like labanotation.
The cloth is powered by temperature differentials and
movement and shares the power among its units along
Note that this is not nanotechnology. The size of each unit
is around a hundred microns in diameter. It consists of a
gimbal combined with sensors to record position, a battery,
a central wire along which surplus power can be sent, a
contractile socket to lock the segment, a thermocouple,
piezoelectric crystals, a transmitter, a receiver and a
processing unit similar to a CPU with a small instruction

or possibly fiber as block based snake robots, ultraminiaturized. I think 300 "threads per inch" is ok as it is apparently deluxe for sheets.

||I very much like the idea of a fabric in which each short piece can be programmed to (try to) orient itself in a particular way.
||You'll struggle to make it in 100 microns, but you might be able to make rice-grain-sized modules.
||// Note that this is not nanotechnology. The size of each unit is around a hundred microns in diameter. //
||So it is nanotech, but just on a bigger scale.
||<ponders m-f-d'ing the idea>
||<ponders likelyhood of [19thly] going postal>
||<decides aganst m-f-d, for now>
||So, by the logic used above, all tech is nanotech, just that some is bigger than others.
|| <ponders likelyhood of [8th] going postal>
||Decides to post this anyway.
||I'm still uncertain as to the base technology upon which this is
created. Electro-active polymers perhaps?
||or possibly the fiber as block based snake robots[link], ultraminiaturized.
||I think 300 "threads per inch" is ok as it is apparently deluxe for sheets. That is far from nanotechnology
||Also far from manufacturable, given the battery craziness.
||Dyson spheres are nanotech too then?
||Absolutely not but relative to our galaxy, yes.
||Now, if we only knew how molecules fold shape as patterned charge moves along long molecular chains this might be viable.
||I had in mind some kind of etching process akin to the
manufacture of integrated circuits which would produce the
likes of cogs and gears. I realise this isn't enough.
||Oh God, don't get me started [notexactly]! I was confronted
with this yet again when I came across hoodie strings with
earbuds in them the other day. It just brings incredibly
stinky, stained people up on one side and fools with broken
clothing on the other.
||So yes it is machine washable but I've no idea how. It just
has to be.
