Although most flexible piezoresistive sensors are realized through heterogeneous conductive media for large deformability and piezoresistivity [46], here we start with the piezoresistive effect in metal conductors and semiconductors to understand the basic mechanisms. First, let’s take a metal conductor wi...
lightweight devices that incorporate accelerometers based on microelectromechanical systems technologies1. The device in this study comprises a collection of functional components, encapsulated and supported by an elastomer and interconnected with serpentine conductive traces that maximize the measurement...
Furthermore, the resonance frequency of metasurface is distributed from radio to terahertz (THz) [5], [6], making its application field more widely than other conventional materials. Compared with three-dimensional metamaterials, metasurface is easier to manufacture, integration and has sufficient ...
This makes acoustic-based sensing and WiFi-based sensing a valu- able complement to each other. Based on the sound wave sensing, the hardware base mainly includes two components: microphone and speaker. With the popu- larity of mobile devices and wearable devices, widespread deployment of ...
Sensors utilize a wide spectrum of transducer and signal transformation approaches with corresponding variations in technical complexity. These range from relatively simple temperature measurement based on a bimetallic thermocouple, to the detection of s
For reference, acoustics is typically categorized into divisions: infrasound, audible sound, and ultrasound, as well as three specialized studies related to each frequency range: infra-acoustics (<˜20 Hz, or 20 cycles per second, below hearing threshold of a human ear), audible acoustics (...
Preferably, user computer device 102 is a wireless mobile device, such as a cellular telephone, a radio telephone, a smart phone, or a personal digital assistant (PDA), a laptop computer or a tablet computer with radio frequency (RF) capabilities, or any other handheld or portable electronic...
detecting electrical signals of the heart tissue at the treatment site with an electrode array of the catheter, wherein the electrode array is disposed on the plurality of splines of the catheter and in a sensing configuration; determining whether the catheter is at a region of interest by analy...
Occupant position sensor system for a driver of the vehicle in which a sensor is arranged on or incorporated into a steering wheel assembly and provides an output signal which varies as a function of
