Frequently Asked Questions
1、Classification and Definition of Flexniss' Flexible Sensors？
Our flexible sensors are divided into two major categories: flexible thin film pressure sensors and far-infrared flexible heating fabrics.Among them, flexible thin film pressure sensors are divided into flexible piezoresistive sensors and flexible piezoelectric sensors.
（1）Definition of flexible piezoelectric sensor
It converts external pressure signals into voltage signals for output through the piezoelectric effect of flexible sensing materials, realizing the detection of pressure.
（2）Definition of flexible piezoresistive sensor
It converts external pressure signals into resistance signals for output through the piezoresistive effect of flexible sensing materials, realizing the detection of pressure.
（3）Definition of far-infrared flexible heating fabric
By preparing a carbon nanomaterial film on a flexible fabric substrate and utilizing the far-infrared characteristics of carbon nanomaterials to form a unique heating mechanism. After passing direct current, the heating film releases far-infrared waves of 2-20 um. Not only is the electrothermal conversion efficiency high, but it also coincides with the far-infrared wavelength range of the human body. It conducts heat better to the human body and has physiotherapy effects at the same time.
2、What's the working principle of the flexible thin film pressure sensor?
The flexible thin film pressure sensor is a sensing device that can convert external pressure into electrical signals (voltage, resistance, current, capacitance) for output. Its working principle is to convert external pressure signals into electrical signals for output through the pressure-sensitive characteristics of flexible sensing materials. The output electrical signal changes with the change of pressure applied on the sensor surface. Through a specific pressure-electrical signal relationship, the pressure magnitude can be measured.

2、Array distributed detection system Leanscan（MF8080-Handle)
Leanscan is a high performance pressure distribution detection system mainly used to detect the pressure distribution between two contact surfaces.
The system consists of three parts: array sensor, collector and upper computer system. The sensor is made of flexible materials with high flexibility, ultrathin and bending resistance, and can accurately measure and analyze the pressure distribution data between contact surfaces.
The pressure distribution can be displayed in the form of a two dimensional heat map to show the pressure magnitude, or can be displayed in real time in a three-dimensional form.
The upper computer system has specific image saving and video saving functions and supports exporting data for data analysis and secondary development.
