Abstract: Low drift force sensing conductors include small conductive balls in the ink used to create the conductor. The use of conductive balls reduces sensor drift while avoiding unwanted side-effects like temperature sensitivity. The conductive balls are made of sized synthetic graphite, a derivative of petroleum pitch or coal tar or any other suitable substance. Force sensors incorporating these balls also demonstrate enhanced sensitivity to low forces.

Abstract: Pre-loaded force sensitive input devices, force sensing resistors (FSR), are formed as a multiple membrane assembly that is capable of detecting low intensity pressure inputs and quantifying varying applications of pressure to the sensor surface. Pre-loading the force sensor elements results in a controlled amount of force between the two substrates causing a constant state of pre-load and eliminating the low-end or minimal pressure signal noise associated with unloaded sensors. Pre-loading the force sensing resistor sensor also enables the sensor to detect removal of low intensity pressure input such as might occur during theft of light weight articles placed in contact with the pre-loaded force sensor. Using an FSR or FSR Matrix Array will enable any handling of protected retail packaging to be detected and identified. A library of “touches” can be established that will yield cutting, ripping, twisting, etc. making the detection of a theft in progress more accurate.

Abstract: Hybrid force sensitive input devices are formed as a membrane assembly that is capable of detecting capacitive presence near the sensor surface as well as pressure inputs and varying applications of pressure to the sensor surface. As a capacitive sensor, the electrical charge of a user's hand, finger or other extremity is sensed by the conductive layers of the sensor as a function of the input extremity's location and proximity to the sensor surface. As a force sensor, a user's input contact with the sensor surface is detectable when conductive elements on apposing substrates are forced into contact when input force is applied. Increasing the applied force increases the number of conductive particles making contact allowing the electrons to travel from one conductive trace on a first substrate through the contacting conductive patches to a perpendicular conductive trace on a second substrate.
