Demo of body pressure mapping and dynamic gait measurement is presented in this post.
We concatenated several MC1600 electronics and MS9705 sensors to build large sensors for this purpose.
Active sensing areas of sensors for gait measurement and body pressure mapping are 384 x 1,536 mm and 768 x 1,536 mm, respectively.

A simple wireless pressure mapping system is implemented using Kitronyx Snowboard 2.
Snowboard 2 is a low cost data acquisition electronics for FSR matrix sensors and able to work as a Arduino shield.
In this demo, Snowboard 2 is combined with Arduino Uno and Bluetooth shield to send pressure mapping data to an Android smartphone in which a custom built app visualizes the pressure mapping data.

In this video, we demonstrate pressure mapping while a user sits on a chair using Kitronyx entry level pressure mapping solution MP2509.

This product is suitable for developing pressure mapping system for seating.

We posted smart sensor insole demo previously with low profile visualization.
In this demo, we upgraded the visualization performance of our software (Snowforce 3).
Smart sensor insoles are configured inside shoes and foot pressure data is gathered by Snowboard 2 data acquisition electronics.

This body pressure mapping data was acquired by Kitronyx pressure distribution measurement solution.
In order to build a large intelligent sensor mat, we used eight MS9705 FSR matrix sensors and eight MC1600 data acquisition electronics.

Total size of sensor is about 1,536 mm x 768 mm and sensor resolution is 192 x96.

In previous post, we compare measurements of pressure mapping system and pressure indicating film.

We further compare pressure indicating film and pressure mapping system (pressure distribution measurement system).

At this time, dynamic pressure is applied to two measurement systems and results are compared.

Since pressure indicating film is designed for static pressure sensing, this device not suitable to measure dynamic pressure distribution measurement. 

In addition, even though we used very sensitive pressure indicting film, it did not capture pressure mapping very well while pressure mapping system shows reasonable sensitivity in measuring pressure.

Force images from a pressure mapping system and pressure indicating film are compared.

MC1600 data acquisition electronics for FSR matrix sensors and MS9758 square FSR matrix sensor comprises a pressure mapping system.

In the video, it is clearly shown that two pressure map images are very similar. That is, pressure mapping systems are very useful digital counterpart of pressure indicating film.

In this video we show dynamic foot pressure mapping using our MP2512 smart sensor insole development kit.

MP2512 comes with two FSR (Force Sensing Resistor) sensor insoles which are insole shaped FSR matrix sensors. On the sensor 160 pressure sensing pixels are disposed to provide high resolution footprint force image.

This product also include Snowboard 2 – low cost pressure mapping electronics.

​With Kitronyx API, a developer can easily capture foot pressure distribution data and send it to another application via TCP/IP.

It's the era of IoT (Internet of Things). Here we user force sesnsitive resistors (FSRs) to build an smart warehouse prototype. In this prototype, we use Snowboard 2 and a few single-zone FSR sensors.
