Enables autonomous driving of a 2 or 4 wheel car with an Arduino and a Adafruit Motor Shield V2. To avoid obstacles a HC-SR04 Ultrasonic sensor mounted on a SG90 Servo continuously scans the area.

This paper presents a comprehensive review of solid-state metal pH sensors, with an emphasis on the potential of metal nitrides to address the limitations of glass electrodes and metal oxides. Metal ...

Abstract: Flexible strain sensors based on liquid metal have great application potential in wearable devices, biomedicine and soft robots due to their huge deformability, low hysteresis and high ...
