We are working on an assistive robotic system for elderly. We need to know maximum weight that a human chest can bare. It would be grateful if I get links to associated literature.
This type of data can be found in automotive injury type publications. I cannot remember his name but there was an american engineer who used to hit himself in the chest with hammers etc at the start of this research, I think it was for General motors. However, automotive standards and test centres have this info to hand, eg MIRA in the UK, as do companies such as volvo (who pioneered seat belts)....no need to redesign the wheel just look out this type of data. Also a good data search for automobile trauma will supply the info you need.
The last obvious point of call is CPR data, this data will be given somewhere too.
