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.

Prof. S. Y Heo at College of Veterinary Medicine, Chonbuk National University applied Kitronyx MC1509 data acquisition electronics and MS9706 fine pitch FSR matrix sensor for capture surface pressure between animal joints.

This thin fine pitch MS9706 sensor provides qualified data and analysis of joint function. Kitronyx thin film pressure sensors are available in various sizes, and configurations for versatility and ease of use.

The combination of MC1509 and MS9706 gives pressure mapping and contact area between adjacent articulating bones for better understanding of their operation.

Note: MC1509 has been discontinued and replaced with MC1600.

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.

Snowboard 2 and MS9723 FSR (force sensing resistor) tactile matrix sensor are collectively used to sense the tilt and misalignment of nip roller.

Snowboard 2 is a very cheap data acquisition electronics for FSR matrix array sensors but enough to get pressure map data from MS9723 tactile sensor sandwiched between two rollers.

This video guide will make you know how to use Snowboard 2 within 5 min.
