Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

Abstract: This paper reports a novel composite high-frequency vision-based tactile sensor with an embedded transparent MEMS-based piezoelectric module. Taking advantage of the transparency of the ...

Abstract: In this letter, we report an ultrasensitive pressure sensor based on an integrated circular piezoelectric microelectromechanical resonator and stainless-steel diaphragm structure.

This project uses an WEMOS D1 Mini ESP8266 module and an Arduino sketch to connect to a NTP (Network Time Protocol) server to automatically retrieve and display the local time on a inexpensive analog ...

Belay is a sensor for FFF 3D printers for keeping a secondary extruder in sync with the primary extruder, avoiding error accumulation regardless of how long a print ...
