With inspiration from Dunko Yoon's kinetic rings, this form seeks to create physical movement in response to an input via a sensor.
Gold indicates brass, grey indicates felt. The cotton string is found threaded through the holes on the pieces of brass on the right.
The object is to be worn on the hand, so that the person themselves experiences the analogue physically. The box to the right is worn around the index and ring finger, and the felt to the left is strapped on to the wrist.
The string leading away from the wrist strap is the wiring connected up to the neckpiece worn by the person. Between the wrist strap and the tube on runners is flexinol. Between the tube and the brass planes is cotton string.
The mechanism works such that when a current is sent down the wire, the flexinol contracts and pulls the tube. This tube then pulls the cotton string and the brass planes flips up like a see-saw. The purpose of this movement, as well as the thread that will be hanging from the plane, is that it mimics an animals skin/hair reaction to someone close to them - such as when hairs stand up on your neck when you "feel" someone behind you.
The piece will have cotton threads threaded through tiny holes in the brass - a reference to hairs standing on end/hairs/skin structure/epidermis/wings. The intent is to try keep the structure as light/simple as possible.
The main problem I am finding in the design of this is how to keep the nitinol from touching the brass, as I am worried the brass will overheat or short the circuit. I've attempted to solve this by having a brass tube insulated with felt that is placed on runners. The string that pulls on my "wing" is simple cotton thread and is connected to the insulated tube. The nitinol also connects to this tube, so that when it contracts, it pulls the tube and cotton thread.
