Strain Gauges: Structure, Working Principle and Common Types
16 December 2020
Strain gauge is a device that changes resistance with force; it converts physical quantities such as force, pressure, tension, and weight into changes in resistance to measure these physical quantities. When an external force acts on a fixed object, stress and strain are generated. The reaction force (external force) generated inside the object is the stress, and the displacement and deformation generated are the strain.
What are the Different Types of Fingerprint Sensors?
16 December 2020
A fingerprint sensor is a key device to realize automatic fingerprint collection. Fingerprint sensors are classified into optical fingerprint sensors, semiconductor capacitive sensors, semiconductor thermal sensors, semiconductor pressure-sensitive sensors, ultrasonic sensors, and RF sensors according to the sensing principle.
Switch-mode Power Supply Basics
14 December 2020
Switched-mode Power Supply (SMPS), also known as switching converter, is a high-frequency electric energy conversion device and a type of power supply. Its function is to convert a level of voltage into the voltage or current required by the user through different forms of architecture.
What is a Thyristor?
11 December 2020
Thyristor, also known as silicon controlled rectifier (SCR), can control its conduction through a signal, but cannot control its turn-off, so it is called a semi-controlled device. The name thyristor often refers specifically to a basic type of thyristor, but broadly speaking, thyristors also include many derivative devices, such as Tri-Electrode AC switch (TRIAC), Fast Switching Thyristor (FST), Reverse-Conducting Thyristor (RCT) and Light-Triggered Thyristor (LTT).
An overview of Flip-flop
10 December 2020
Flip-flop is an electronic component that can store the state of a circuit. The memory cell circuit that can only act when triggered by a clock signal is called a flip-flop to distinguish latches that are not controlled by a clock signal.
What is Mini LED?
08 December 2020
Mini LED is defined as an LED device with a chip size between 50~200μm. The size of the Mini LED is between the small-pitch LED and Micro LED, which is the result of further refinement of the small-pitch LED. Mini LED can be used as a backlight source in products such as large-size displays, smartphones, car panels, and gaming notebooks. It can also be used as a self-luminous display with RGB three-color LED chips.

Basic Introduction to Filter Capacitor
05 December 2020
The filter capacitor refers to an energy storage device installed at both ends of the rectifier circuit to reduce the ripple coefficient of AC pulsation and improve the efficient and smooth DC output.
What are Memory Chips?
03 December 2020
Memory chip is the specific application of the concept of embedded system chip in the memory industry. Therefore, whether it is a system chip or a memory chip, it is through embedding software in a single chip to achieve multi-function and high performance, as well as support for multiple protocols, multiple hardware, and different applications.
What are Comparators?
03 December 2020
Comparing two or more data items to determine whether they are equal, or determining the size relationship and arrangement order between them is called comparison. A circuit or device that can realize this comparison function is called a comparator.
Basic Introduction to System on a Chip
02 December 2020
System on a chip is generally called SoC, also called system-level chip. It is a product or an integrated circuit with a dedicated target, which contains a complete system and all the contents of embedded software. It is also a technology to realize the whole process from determining the system function to the software/hardware division, and completing the design.
What are TPMS Sensors?
21 November 2020
TPMS stands for "Tire Pressure Monitoring System". It is mainly used to automatically monitor tire pressure in real-time when the car is driving, and to alarm tire leaks and low pressure. Each car tire is equipped with a TPMS sensor connected to the tire valve, which regularly measures tire pressure, temperature, and acceleration information and is converted into digital form by the MCU in the TPMS sensor.
