The force or pressure sensor array of the present invention effectively has both flexibility and elasticity. Since the substrate itself is a kind of a polymer material, the substrate can be bent or expanded. Although silicon, which is a material of the semiconductor strain gauge, is easily broken and solid, mechanical flexibility can be secured if it is fabricated extremely thin. To this end, particularly, disclosed is a flexible force or pressure sensor array using semiconductor strain gauges, the sensor array comprising: a substrateincluding: the semiconductor strain gaugesin which a plurality of elements formed in a certain array pattern is deformed by force or pressure, a pair of polymer film layersandhaving film surfaces contacted facing each other and containing the semiconductor strain gaugebetween the film surfaces contacted with each other, and a pair of signal line layers formed on top and bottom surfaces of an insulating layer using either of the pair of polymer film layersandas the insulating layer and connected to the elementsof the array pattern to form electrodes, for fetching deformation signals outputted due to deformation of the elementsto outside; and a pair of elastomer layersandformed on both sides of the substrateto contain the substrateinside.

Disclosed herein are a mouse with capacitance sensors, a method for manufacturing the mouse and a method for constructing an algorithm for processing an input corresponding to force applied by a user's finger to the mouse. The mouse with capacitance sensors includes a bottom plate having a center point, a plurality of electrodes formed at regular intervals on the top face of the bottom plate and arranged apart from the center point of the bottom plate by an equal distance, a top plate bonded to the top faces of the electrodes and deformed by force applied by a pointing object, and an adhesive layer formed around the top plate and the bottom plate to combine the top plate and the bottom plate. When the pointing object touches the top plate, capacitance sensors are formed between the pointing object and the electrodes to recognize a travel distance, a travel direction and a moving speed of a cursor through the magnitude and direction of force applied by the pointing object.

A method of and an apparatus for reproducing texture, in which a garment product designed by a designer is reproduced using a computer. A visual texture of the product is reproduced by applying the reproduced product to a virtual model, and displaying the virtual model, on which the product is put, on a screen. A tactile texture of the product is also reproduced by driving a tactile texture reproducer based on the surface characteristics, softness and heat transfer coefficient of a fabric to be applied to the product. Based on the reproduced visual and tactile textures, consumers experience the virtual texture of the product through their virtual and tactile senses. Accordingly, it is possible to positively reflect opinions of consumers on products being developed. This makes it possible to develop products having a better chance of market success while reducing the labor, time and costs required in the developments of products.
