The present invention relates to a touch screen, and particularly to a pressure-sensitive touch screen and an electronic device. The present touch screen comprises a substrate which has an elastic deformation performance and is used by a user to operate and a strain sensor which is used for detecting lateral deformation of the substrate and is fixedly arranged at a peripheral location of a lower surface of the substrate, and further comprises a pressure bearing plate, wherein the pressure bearing plate is fixedly arranged at an upper surface of the substrate, and the location where the side edges of the pressure bearing plate are projected onto the strain sensor is located at a middle location of the strain sensor. Also provided is an electronic device containing the pressure-sensitive touch screen. By way of detecting a lateral deformation amount of the substrate, the present invention thus recognizes a touch location and a touch pressure value, provides a pressure-sensitive operation function for a user and can adapt to different input methods, without being limited by the touch form.

An electronic device includes a proximity-sensitive touch sensor array which extends along an input surface of the electronic device and a processing device coupled to the touch sensor array. The processing device is configured to process data captured by the touch sensor array to determine a finger angle at which a finger is directed towards the input surface and an actuation position on the input surface. The processing device is configured to establish an offset-corrected actuation position as a function of the actuation position and the finger angle.

The present invention discloses an electronic device that uses separate surfaces for input and output. One of the surfaces (e.g., the bottom) includes a force-sensitive touch-surface through which a user provides input (e.g., cursor manipulation and control element selection). On a second surface (e.g., the top), a display element is used to present information appropriate to the device's function(e.g., video information), one or more control elements and a cursor. The cursor is controlled through manipulation of the back-side touch-surface. The cursor identifies where on the back-side touch-surface the user's finger has made contact. When the cursor is positioned over the desired control element, the user selects or activates the function associated with the control element by applying pressure to the force-sensitive touch-surface with their finger. Accordingly, the electronic device may be operated with a single hand, wherein cursor movement and control element selection may be accomplished without lifting one's finger.

A flexible conductive film, which relates to a conductive film, comprises two layers of flexible transparent films, two graphene conductive layers are arranged between the two layers of flexible transparent films, transparent insulating points are arranged between the two graphene conductive layers, and the flexible conductive film can be used in the production of resistive touch screens. Since the invention adopts graphene to replace ITO (indium tin oxide) as the material of the conductive film and the transparent insulating points are arranged between the two graphene conductive layers, when no pressure is applied, the two graphene conductive layers are separated from each other under the support of the transparent insulating points; after pressure is applied, the two graphene conductive layers are in contact with each other to conduct at the position where pressure is applied, so that an electric signal is generated; and the touched position is detected by a control circuit, so that touch operation is conducted. The touch screen made of graphene has the advantages of sensitive touch response, high light transmittance, high conductivity, low cost and environment-friendliness.

The invention belongs to the technical field of production of condoms, and in particular relates to a condom using modified biological starch as a separant and a preparation method of the condom. The condom is prepared by preparing separant suspension, which is used for replacing the conventional precipitated white carbon black separant suspension, by using the modified biological starch and a specific auxiliary agent by the conventional condom preparation process. Compared with the conventional condom using white carbon black as the separant, the condom has the advantages that: the surfaces of internal and external glue films are adhered with a separant with higher content which averagely reaches 50mg/piece approximately, so that a gap between the condom and an electrically-detected curled rear glue film is enlarged, the adsorption pull-up speed of a lubricant is increased, and the effect of penetration of the lubricant on the surface of a condom glue film is achieved; simultaneously, more sensitive touch feeling of the condom is endowed by the modified biological starch, and the lubricating effect of a customer during use is greatly improved, so that the condom can be easily accepted by broad customers during popularization and use.
