Without any delays, here are the best Phones with Ultrasonic Fingerprint Sensors (January 2026) that make the cut: ...

Abstract: We propose a one-millimeter-scale linear ultrasonic motor and its feedback control system with a Hall sensor. The size of the stator measures 1.6 mm in height, 1.6 mm in width, and 0.3 mm in ...

Abstract: Proximity sensing is of great importance for robot control during human–robot collaboration (HRC). Commonly used machine vision sensors or photodetectors are subjected to the light block ...

Arduino library for the I2C LCD display, typical 20x4 characters. The library is inspired by the excellent New-LiquidCrystal library by F. Malpartida. Therefore the interface is kept quite identical, ...

Is a human micro-motion sensor that can detect and recognize moving, standing, and stationary human body. The code in this library is based heavily off this LD2410, Waveshare and RD-03 documentations.
