Massage chairs are important equipment for modern family health care and driving comfort, in which the pressure sensor plays a key role. Pressure sensor is a device that can sense and measure pressure changes, it is used in massage chairs to monitor the process of airbag inflation to control the size of the massage force.
Next, we will explain the WF company’s R & D and production of high-precision WF100DP pressure sensor in the wisdom of the massage chair actually play what role.
Let’s start reading!
In the massage chair, the airbag is inflated by a pneumatic pump, which generates mechanical squeezing pressure to simulate the massage action of human fingers. Le pressure sensor is responsible for monitoring the inflation process and transferring the information of inflation pressure to the control system. Generally speaking, the pressure of the air pump is between 30Kpa and 70Kpa, and the duration of inflation determines the size of the airbag pressure.
Through the pressure sensor’s measurement of the airbag pressure, the control system of the massage chair can accurately control the length of inflation time. When the pressure sensor senses that the pressure of the airbag reaches the set value, the control system will stop the work of the air pump, so as to achieve the preset massage intensity. If more massage force is needed, the control system will extend the inflation time; on the contrary, if less force is needed, the inflation time will be shortened.
The use of pressure sensors allows the massage chair to adjust the intensity of the massage according to individual needs and preferences, thus providing a more comfortable and personalized massage experience. Whether it is a gentle relaxing massage or a strong deep massage, the pressure sensor can automatically adjust the inflation time of the massage chair according to the user’s choice, ensuring that the massage intensity meets his/her expectations.
En outre, the pressure sensor can also play the role of safety protection. When the massage chair appears abnormal or exceeds the reasonable pressure range, the pressure sensor can detect it in time and send a signal to the control system to trigger an emergency stop or alarm. This can effectively prevent accidental injuries that may occur during the massage process and protect the user’s safety.
As a leading MEMS sensor manufacturer, WF has independently developed the following sensors for all types of massage chairs on the market:
WF Series Pressure Sensors: This sensor is a calibrated capteur de pression relative that combines WF’s own intellectual property MEMS piezoresistive chip with a dedicated signal conditioning chip that undergoes signal amplification, calibration, and multi-stage pressure and temperature compensation. Suitable for consumer, medical and other applications. The standard SOP6 package can be directly soldered to the circuit board and supports proportional/absolute analog voltage output.
WF Series Pressure Sensor: This sensor is an integrated digital output pressure sensor with features of miniaturization, high accuracy, high sensitivity, and high reliability. The pressure sensor MEMS chip and signal conditioning chip are integrated internally to digitally compensate for the sensor’s zero point, sensibilité, temperature drift and non-linearity, and output a calibrated, temperature-compensated standard I2C signal. SOP package, RoHS compliant, easy for customers to solder and install, widely used in medical electronics, automotive electronics, sports and fitness equipment and other fields.
FIN
En bref, by using the above pressure sensors in massage chairs, the massage intensity can be intelligently adjusted according to the user’s needs, providing a personalized massage experience, which not only improves the comfort and effect of the massage chair, but also ensures the safety of the user. En outre, the above sensors also play an important role in the industrial, medical, home appliance and consumer sectors, helping to innovate applications and create product value.
