CUI has three new micromachined omnidirectional microphones for portable devices and wearables, that can work across 20 to 20,000 Hz. CMM-2718AB-38162W-TR, CMM-2718AB-38164W-TR and CMM-2718AT-38164W-TR are analogue mems microphones with accurate -38dB ±1dB sensitivity ratings. There are top or bottom port versions, in packages down to 2.75 x 1.85 x 0.9mm,...

The femtosecond GHz-burst mode laser processing has attracted much attention in the last few years. Very recently, the first percussion drilling results obtained in glasses using this new regime were reported. In this study, we present our latest results on top-down drilling in glasses, focusing specifically on the influence of...

The techniques that harvest mechanical energy from low-frequency, multidirectional environmental vibrations have been considered a promising strategy to implement a sustainable power source for wireless sensor networks and the Internet of Things. However, the obvious inconsistency in the output voltage and operating frequency among different directions may bring a hindrance...

Selective laser melting (SLM) is a three-dimensional (3D) printing process that can manufacture functional parts with complex geometries as an alternative to using traditional processes, such as machining wrought metal. If precision and a high surface finish are required, particularly for creating miniature channels or geometries smaller than 1 mm,...

A safety and arming device with a condition feedback function has been designed in this article to improve the intelligence and safety of ignition devices. The device achieves active control and recoverability by virtue of four groups of bistable mechanisms which consist of two electrothermal actuators to drive a semi-circular...

The three-body coupling grinding mode of a ball ensures the batch diameter variation and batch consistency of precision ball machining based on the principle of ball forming, resulting in a structure that is simply and feasibly controllable. The change in the rotation angle can be jointly determined using the fixed...

Viele autonome Fahrzeuge verlassen sich auf IMUs für die Navigation. Hier zeigen wir, wie das MEMS-Modul Ihnen bei der Modellierung der in IMUs verwendeten Gyroskope und Beschleunigungsmesser helfen kann....

Learning from the locomotion of natural organisms is one of the most effective strategies for designing microrobots. However, the development of bioinspired microrobots is still challenging because of technical bottlenecks such as design and seamless integration of high-performance actuation mechanism and high-density energy source for untethered locomotion. Directly harnessing the...
