摘要： Le module de récupération d'énergie comprend dans un tube enveloppe (50) un ensemble pendulaire comprenant une lame (22) de transducteur piézoélectrique, une masse inertielle (26) couplée à l'extrémité libre de la lame, et une monture de lame (54) solidarisée au tube et fixée à une pièce d'encastrement (24) de la lame. Le module comporte en outre un insert de symétrisation (56) pour le calibrage et la symétrisation des oscillations de l'ensemble pendulaire en direction transversale et latérale. L'insert de symétrisation (56) est distinct de la monture de lame (54) et comprend une partie périphérique (60) solidarisée au tube (50) de façon indépendante de la monture de lame (54), et une partie centrale avec une cavité axiale traversante (74) à l'intérieur de laquelle s'étend la lame (22) dans une région de libre débattement. La cavité axiale s'étend entre des surfaces de limitation de course (76) en vis-à-vis, qui sont symétriques et sont aptes à venir en contact avec la lame (22) dans une configuration de flexion de celle-ci.

摘要： To suppress change in a surface resistance value under a high-temperature or high-humidity environment in a transparent conductive piezoelectric film including a transparent piezoelectric film made of a fluororesin. A transparent conductive piezoelectric film (10) includes a transparent piezoelectric film (1) made of a fluororesin, a transparent coating layer (2), and a transparent electrode (3) stacked in this order. The total thickness of the coating layer (2) is 0.6 to 4.5 µm. When the transparent conductive piezoelectric film (10) is left to stand in a specific high-temperature environment, the ratio of a resistance value after being left in the environment to a ratio of a resistance value before being left in the environment is 1.30 or less.

摘要： Sensor assemblies for electronic devices are described. According to some embodiments, the sensor assemblies include solid-state sensors, such as capacitive sensors, piezoelectric sensors or piezoresistive sensors. The sensor assemblies can include a number of features that provide a compact profile, making them well suited for integration into small spaces of electronic device enclosures. The sensor assemblies can also include features that isolate movement of various parts of the sensor assemblies, allowing for accurate detection of a sensing event. According to some embodiments, the sensor assemblies are coupled to haptic actuators, speaker, or both, which mimic the feel of a mechanical button and enhance a user's experience.
