What is a Tactile Sensor?
Form: :Alan
2021-10-21 00:00:00
Tactile sensation is a general term for mechanical stimuli such as contact, sliding, and pressure sensation. Different parts of the skin have different tactile sensations for different things because the number and type of different receptors are distributed. The human face, lips, fingers, and other parts of the body have a lot of receptors, so these parts of the body are very sensitive.

Classification and Application of UV Sensor
Form: :Alan

The human five senses are "sensors" with very complex and sensitive functions. However, most of the human five senses can only perceive information from the outside world qualitatively, but not quantitatively. In addition, there are many physical quantities that cannot be felt by the human. For example, they can perceive the visible part of the vision, but they cannot perceive the non-visible spectrum with a wider frequency domain. With the help of infrared and ultraviolet sensors, these invisible lights can be sensed.

What is Visible Light Communication(VLC)?
Form: :Rose
2021-10-13 00:00:00
In some situations, visible light communication (VLC) has considerable advantages over the more generally utilized radio frequency (RF). VLC has gained a lot of attention because of its ability to provide a very accurate and safe indoor positioning system, in addition to the obvious usage of data transmission from one location to another. Implementing a VLC system poses unique hurdles in terms of system integration and power management, particularly for people unfamiliar with the technology. This article will look at some of the uses of VLC, as well as the fundamentals of the VLC positioning system, and how the most recent devices offer a low-risk design approach.

Introduction to Optical Amplifier
Form: :Alan
2021-10-13 00:00:00
An optical amplifier is a subsystem product that can amplify optical signals in optical fiber communication systems. The principle of the optical amplifier is basically based on the stimulated radiation of the laser, which realizes the amplification effect by converting the energy of the pump light into the energy of the signal light.

2021-10-12 00:00:00
In industrial process control, measurement and transmission unit, actuator, and regulator are the three major components of the entire control system. Among them, the measurement and transmission unit is the transmitter, and sometimes the transmitter is actually equivalent to the sensor. The actuator is like a valve, and the regulator is the controller, which is the brain of the entire control system.

Silicon carbide (SiC) and gallium nitride (GaN), who is the future of wide bandgap (WBG) materials?
Form: :Rose
2021-10-07 00:00:00
So far, semiconductor materials have gone through three stages of development: silicon (Si) is the first-generation semiconductor, arsenide (GaAs) is the second-generation semiconductor, and wide band gap semiconductor is the third-generation semiconductor (WBG). Silicon carbide (SiC) and gallium nitride (GaN) are two types of semiconductors (GaN). Although there is no saying in this field that "the last wave beats the front wave, the front wave dies on the beach," the third generation semiconductors represented by GaN and SiC are in the early stages of development, and first and second generation semiconductor materials such as Si and GaAs are still available. In the industry, there is a large-scale application. Third-generation semiconductors, on the other hand, have significant performance advantages.
