The pressure-sensitive function of the Capacitive pen nib is achieved through a series of sophisticated mechanical and electronic designs, which allows users to achieve changes in line thickness, depth and other effects based on different strengths when writing or drawing.
First of all, the Capacitive pen nib has a pressure sensor embedded inside it, which is a key component to achieve the pressure sensing function. Pressure sensors usually operate on a capacitive or resistive principle. When a user writes or draws with a capacitive pen, the tip of the pen comes into contact with the screen. As the applied pressure changes, the pressure sensor can sense this change.
For capacitive sensors, it uses changes in capacitance to sense pressure. When pressure is applied, the distance between the positive and negative terminals of the capacitor inside the Capacitive pen nib changes, thus changing the capacitance value. This change in capacitance is captured by the sensor and converted into an electrical signal output.
Resistive sensors, on the other hand, sense pressure through changes in resistance. When pressure is applied, the resistive material deforms, causing a change in resistance. This change in resistance value is also captured by the sensor and converted into an electrical signal.
These electrical signals are then transmitted to the device's control system. The control system will analyze and process these signals, and judge the amount of pressure exerted by the user based on the changes in the signals. Then, according to the preset algorithms and parameters, the control system will adjust the thickness, depth and other effects of the lines to achieve the pressure-sensitive function.
It is worth noting that the pressure-sensitive function of the Capacitive pen nib requires the cooperation of the device screen to be realized. The device screen needs to have corresponding touch and pressure sensing functions to accurately identify the pressure changes of the Capacitive pen nib and respond accordingly.
In general, the pressure sensing function of the Capacitive pen nib is realized through multiple links such as internal pressure sensors, capacitance or resistance changes, electrical signal transmission, and analysis and processing of the equipment control system. This allows the capacitive pen to more realistically simulate the effect of traditional brush strokes when writing and drawing, providing users with a more natural and rich creative experience.
