Method and apparatus for a flexible housing

1. An apparatus, comprising a housing having a substantially rigid portion and a substantially flexible portion, wherein the substantially rigid portion comprises a plurality of openings, and wherein the substantially flexible portion is at the plurality of openings, and wherein the substantially flexible portion is configured to generate a voltage in response to a bending or twisting of the housing.

2. An apparatus as in claim 1 wherein the substantially flexible portion comprises a substantially flexible material configured to provide haptic feedback in response to a voltage applied at the substantially flexible material.

3. An apparatus as in claim 2 wherein the apparatus further comprises an electrode between a portion of one of the openings and the substantially flexible material and the electrode is configured to apply the voltage.

4. An apparatus as in claim 1 wherein the substantially flexible portion comprises an electro-active polymer.

5. An apparatus as in claim 1 wherein the openings are between castellated or ridged regions of the housing.

6. An apparatus as in claim 1 wherein the openings extend through a majority of a cross-section of the housing.

7. An apparatus as in claim 1 wherein the openings are proximate a lateral side of the housing.

8. An apparatus as in claim 7 wherein the plurality of openings extend along a majority of a length of the lateral side.

9. An apparatus as in claim 1 wherein the apparatus further comprises a display connected to the housing, wherein the substantially flexible portion is configured to flex the housing from a first position to a second position in response to a voltage applied at the substantially flexible portion, and wherein the second position is configured to protect the display.

10. An apparatus as in claim 9 wherein the display comprises a substantially flexible display.

11. The apparatus of claim 1 , further comprising:

at least one processor; and

at least one memory including computer program code;

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following:

provide a haptic feedback to the device, wherein the haptic feedback comprises substantial bending or twisting of the device.

12. The apparatus of claim 1 , further comprising:

at least one processor; and

at least one memory including computer program code;

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following:

generate a voltage for an energy harvesting system of the device in response to a substantial bending or twisting of the device.

13. An apparatus as in claim 1 wherein the apparatus comprises a mobile phone or a wearable device.

14. An apparatus as in claim 1 wherein the substantially flexible portion is configured to provide haptic feedback.

15. An apparatus as in claim 1 wherein the substantially flexible portion is within a space defined by the openings.

16. A method, comprising:

providing a housing, wherein the housing comprises a substantially rigid portion and a substantially flexible portion;

providing a series of openings at the substantially rigid portion, and wherein the substantially flexible portion is at the series of openings; and

providing an electrode at the openings, wherein the electrode is proximate the substantially flexible portion, and wherein the substantially flexible portion is configured to generate a voltage;

wherein the substantially flexible portion is configured to generate a voltage in response to a bending or twisting of the housing.

17. A method as in claim 16 wherein the substantially flexible portion comprises a substantially flexible material configured to provide haptic feedback in response to a voltage applied at the electrode.

18. A method as in claim 16 wherein the substantially flexible portion comprises an electro-active polymer.

19. A computer program embodied on a non-transitory computer-readable medium, the computer program configured to control a processor to perform a method comprising:

generating a voltage at an electrode in response to a bending or twisting of a portable device housing, wherein the electrode is at a substantially flexible material of the housing; and

charging a battery in response to the generated voltage.

20. The computer program of claim 19 wherein the substantially flexible material comprises an electro-active polymer, and wherein the electro-active polymer is configured to provide haptic feedback at the housing.
