What is a Tactile Sensor?
What is a Tactile Sensor?
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
Classification and Application of UV Sensor
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.

Silicon carbide (SiC) and gallium nitride (GaN), who is the future of wide bandgap (WBG) materials?
Silicon carbide (SiC) and gallium nitride (GaN), who is the future of wide bandgap (WBG) materials?
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.

Will HBM replace DDR and become Computer Memory?
The characteristics of high bandwidth and high latency determine that HBM is very suitable for GPU memory. But for personal computers, the tasks to be processed by the CPU are extremely unpredictable, require various random storage accesses, and are inherently more sensitive to latency. So in the short term, it is difficult for HBM to replace DDR on PCs.
