1. A system comprising:
- a film that self-generates an electrical signal in response to an external agent applied to a location on the film; and
a sensor configured to detect the electrical signal at a plurality of positions on the film to determine the location where the external agent is applied to the film.

Abstract
A sensing system and a method of sensing are disclosed. The system includes a film that self-generates a signal in response to an external agent that is applied to a location on the film. The system further includes a sensor that is configured to detect the self-generated signal at a plurality of positions on the film to determine the location where the external agent is applied to the film.

13. A system comprising:
-
a film that self-generates an electrical signal in response to an external agent applied to a location on the film, the self-generated electrical signal producing at least a first detectable signal at a first position on the film and a second detectable signal at a second position on the film; and
a controller adapted to receive at least the first and second detectable signals to determine the location where the external agent is applied to the film. - View Dependent Claims (14)

15. A touch sensor comprising:
a film that self-generates an electrical signal in response to a touch implement applied to a location on the film, the touch location being determined by detecting the electrical signal at a plurality of positions on the film. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A touch sensor comprising:
a film that self-generates an electrical signal in response to a touch implement applied to a location on the film, the touch location being determined by at least a first sensor detecting a first detectable signal produced by the self-generated electrical signal at a first position on the film and a second sensor detecting a second detectable signal produced by the self-generated electrical signal at a second position on the film.
-
35. A method of determining a touch location comprising the steps of:
-
defining a touch sensitive area comprising a film that self-generates an electrical signal in response to an applied touch input;
detecting a plurality of detectable signals produced in response to the self-generated electrical signal; and
using the plurality of detectable signals to determine the touch location.
