Abstract
A method and device is provided for detecting a predetermined material. The device includes a first inner layer having first and second surfaces and a volume responsive to a first predetermined stimuli. A second inner layer has first and second surfaces. An adhesive bonds at least a portion of the first surface of the first inner layer to the first surface of the second inner layer with a bonding force. A change in the volume of the first layer generates an elastic force on the adhesive material. As a result, the first inner layer delaminates from the second inner layer in response to the elastic force overcoming the bonding force.
Claims21
A detection device for detecting a predetermined material, comprising:
- a first inner layer having first and second surfaces and having a volume responsive to a first predetermined stimuli;
- a second inner layer having first and second surfaces and at least a portion of the first surface of the first inner layer bonded to the first surface of the second inner layer with a bonding force;
- wherein:
- a change in the volume of the first layer generates an elastic force on the at least a portion of the first surface;
- and
- the first inner layer delaminates from the second inner layer in response to the elastic force overcoming the bonding force.
A sensing mechanism, comprising:
- a first inner layer having first and second surfaces and first and second ends, the first inner layer having a volume responsive to a first predetermined stimuli;
- and
- a second inner layer having first and second surfaces and first and second ends, the second inner layer having a volume responsive to the first predetermined stimuli, the first surface of the first inner layer bonded to the first surface of the second inner layer with a bonding force adjacent the first ends of the first and second inner layers;
- wherein:
- a change in the volumes of the first and second layers generate an elastic force;
- and
- the first inner layer delaminates from the second inner layer in response to the elastic force overcoming the bonding force.
A method of sensing for use in detecting a material, comprising the steps of:
- interconnecting first and second inner layers with a bonding force;
- and
- exposing the first and second inner layers to a solution;
- wherein the first and second layers separate in response to material in the solution.
