WHAT IS Pressure Mapping?
Pressure mapping is simply the measurement and visual reporting of pressure between two contacting surfaces. In many applications, like in the medical field, pressure mapping technology is used to visualize the contact pressure distribution between the human body and a supporting surface such a seat or a mattress.
There are many uses for pressure mapping in the design and manufacturing of wearable products where comfort and fit are important. The ergonomics or “feel” of a product are critical in the development of products that repeatedly and frequently come into contact with the body.
PPS Pressure Mapping System
The PPS Pressure Mapping System allows users to visualize contact pressure between the body and wearable products or support surfaces. With a PPS pressure mapping interface, product designers and researchers alike can now quantify and visualize the “feel” of a wearable product or body supporting surface.
We create pressure sensing and visualization systems that are both highly accurate and precise to provide the feedback and measurement designers require. Additionally, the contact pressure analysis solutions we create are able to withstand the rigors of testing in both the laboratory and in the field.
PPS has worked closely with many research and development teams to design custom tactile sensing systems and each has been successfully deployed and tested in real-world environments. PPS’s proprietary capacitive sensing technology and full featured visualization and analysis software have provided high-quality results in a wide variety of settings and applications. From head to foot, PPS’s pressure mapping products have met the needs of a wide variety of world-class companies.
APPLICATION: Capture pressures distribution from grasping bicycle handlebars and controls
CUSTOMER: Multinational manufacturer of cycling components
- Customer required collection of high resolution tactile pressure date without having the system interfere with the normal operation of the bicycle.
- Complex system integration
- Upgrade FingerTPS, a single elements solution, to multi array sensing solution
PPS Delivered an integrated two-handed glove solution that comprises of 14 sensor arrays placed on the fingers of each hand coupled with a Stretchable TactArray that was placed on each palm and removable to the bicycle handlebars to cover the region between the thumb and index finger.
Accomplish high resolution tactile imaging of the hand
Portable wireless instrumentation solution for pressure mapping of the fingers
Comprehensive pressure data from the hands in real world live cycling conditions
Application: Diaper Fit
- Measuring fit of a garment against the skin is difficult due to the complex shapes involved.
- P&G needed a tactile sensor solution capable of measuring the fit of a baby diaper.
PPS’s delivered a TactArray solution comprising of molded conformable sensing bands for the waist and legs.
P&G was able to validate the integrity of a diaper seal on a mannequin.
Chameleon software provided 3-D tactile representation of the infant-sized mannequin.
Data quality was not compromised due to the curved surface requirements.
Application: Fruit Ripeness in Squeezing
Customer: Major Avocado Grower
We use our sense of touch at the market to determine which fruits are ripe and good to eat.
The customer wanted to quantify the ideal softness for an avocado.
The FingerTPS system was able to capture hardness or softness from a human hand squeeze.
FingerTPS captured tactile data from a human squeezing an avocado to determine if it was hard, meaning tough texture and flavorless taste, or if the person found one with just the right amount of softness to feel buttery and taste delicious in the mouth.
