Abstract: Ein optisch transparenter Kraftsensor, der Umgebungseffekte kompensieren kann, einschließlich beispielsweise Änderungen der Temperatur der Vorrichtung oder der Umgebungen. Bei einigen Beispielen sind zwei kraftsensible Schichten durch eine kompatible Schicht getrennt. Das relative elektrische Ansprechverhalten der beiden kraftsensiblen Schichten kann verwendet werden, um einen Schätzwert der Kraft einer Berührung zu berechnen, die den Effekt von Temperaturschwankungen reduziert. Bei einigen Beispielen werden piezoelektrische Filme mit anisotropen Dehnungseigenschaften verwendet, um die Temperaturauswirkungen zu reduzieren.

Abstract: An optically transparent force sensor that may compensate for environmental effects, including, for example, variations in temperature of the device or the surroundings. In some examples, two force-sensitive layers are separated by a compliant layer. The relative electrical response of the two force-sensitive layers may be used to compute an estimate of the force of a touch that reduces the effect of variations in temperature. In some examples, piezoelectric films having anisotropic strain properties are used to reduce the effects of temperature.

Abstract: An optically transparent force sensor, which may be used as input to an electronic device. The optically transparent force sensor may be configured to compensate for variations in temperature using two or more force-sensitive components that are formed from materials having different temperature- and strain-dependent responses. 013361\191 1\11707067.1 2122 22 210 222 222 230
