Why Touch Screens Only Respond to Fingers: The Science Behind the Sensitivity

  I. Introduction Touch screen technology enables direct interaction with devices through touch. Using either capacitive or resistive methods, these screens detect user input, translating it into commands. Widely used in smartphones, tablets, and kiosks, touch screens offer intuitive navigation, eliminating the need for physical buttons and enhancing user experience across various applications. Understanding how touch screens work is crucial for users and developers alike. It enhances user experience by ensuring effective interaction, informs choices in device selection, and guides troubleshooting. For developers, knowledge of touch technology is vital for creating intuitive applications and improving interface design, ultimately leading to greater user satisfaction. This blog aims to explore why touch screens predominantly respond to fingers, delving into the science behind touch sensitivity. By examining the principles of capacitive and resistive technology, we will uncover the

steering-angle sensor || How does the steering-angle sensor work?

  What is steering-angle sensor? The steering-angle sensor is based on Giant Magnetoresistance technology (GMR element) and provides an absolute steering-angle value over the complete steering-angle range (multi-turn sensor). A unique feature of this steering-angle sensor is the output of the correct angle within the measurement range directly after ignition-on. Movement of the steering wheel or other measures for initialization of the sensor (True Power-on) is not required even after disconnection and re-establishment of the power supply. No standby current is necessary. The steering angle and steering-angle velocity is made available via CAN interface. Sensor-internal plausibility tests and special self-diagnostic functions allow the use of this sensor in safety systems. The sensor concept also allows the integration of a second microprocessor for safety-related applications.   Why do we need to Measure Steering Angle? The angle of the steering on its own can be used to deter
