1. A stimulus indicating device comprising:
a stimulus sensitive amphiphilic gel contained in a first reservoir; and
an assembly having a first end and a second end and extending in a first direction defining a length of the assembly between the first end and the second end and extending in second direction opposite the first direction defining a width of the assembly, the assembly including:
a top layer,
a middle layer including a porous polymer membrane, and
a bottom layer,
a second reservoir formed between said top layer and said middle layer and being positioned away from said second end, the second reservoir being configured to accept air displaced from said middle layer by movement of said stimulus sensitive amphiphilic gel through said middle layer,
wherein:
said top layer and said bottom layer are sealed together on opposing sides of said assembly, and said top layer and said bottom layer are sealed in the second direction at a widthwise side of the second end of said assembly,
said top layer contains a cover comprising a window,
said stimulus sensitive amphiphilic gel is in fluid communication with said middle layer.
