Abstract: A magnetic nanocomposite device is described herein for a wide range of sensing applications. The device utilizes the permanent magnetic behavior of the nanowires to allow operation without the application of an additional magnetic field to magnetize the nanowires, which simplifies miniaturization and integration into microsystems. In addition, the nanocomposite benefits from the high elasticity and easy patterning of the polymer-based material, leading to a corrosion-resistant, flexible material that can be used to realize extreme sensitivity. In combination with magnetic sensor elements patterned underneath the nanocomposite, the nanocomposite device realizes highly sensitive and power efficient flexible artificial cilia sensors for flow measurement or tactile sensing.

Abstract: A passive and wireless sensor is provided for sensing at least one of magnetic field, temperature or humidity. The sensor can provide only one of the sensing functions, individually or any combination of them simultaneously. It can be used for various applications where magnetic field changes, temperature and/or humidity need to be measured. In one or more embodiments, a surface acoustic wave (SAW) sensor is provided that can measure one or more of a magnetic field (or current that generates the magnetic field), temperature and humidity. In one or more embodiments, a magnetoimpedence (MI) sensor (for example a thin film giant magnetoimpedance (GMI) sensor), a thermally sensitive (for example a Lithium Niobite (LiNbO3)) substrate, and a humidity sensitive film (for example a hydrogel film) can be used as sensing elements.
Abstract translation: 提供无源和无线传感器用于感测磁场，温度或湿度中的至少一个。 传感器可以单独提供感测功能中的一种，也可以同时提供任意组合。 它可用于需要测量磁场变化，温度和/或湿度的各种应用。 在一个或多个实施例中，提供能够测量磁场（或产生磁场的电流），温度和湿度中的一个或多个的表面声波（SAW）传感器。 在一个或多个实施例中，磁阻（MI）传感器（例如薄膜巨磁阻（GMI）传感器），热敏感的（例如锂亚铁（LiNbO 3））衬底和湿敏膜（例如， 水凝胶膜）可用作感测元件。
