When university engineering departments need to test and measure cutting edge innovations, theories and prototypes, who do they call?
At The Load Cell Shop, we supply major universities in the UK and abroad with standard and bespoke load cells for cutting edge research and development projects, as well as student projects and dissertation work.
Load cells for universities
We work with the departments to help supply, or design and manufacture load cells for some truly cutting edge work, from field robotics to motion control, life and health sciences, and sports science. We’ve also supplied load cells for numerous projects in mechanical / civil engineering and material sciences departments.
Exciting exoskeleton research in Gent
It’s hard to pick out just one project from so many, but one that gained worldwide attention was an exoskeleton developed by a team at the University of Gent (Ghent) in Belgium to assist a crucial part of walking.
In their paper (1), the team described how they has focussed on the amount of energy required for plantarflexation (extension of the ankle and/or pointing of the foot) at the point when the opposite leg heel makes contact with the ground.
“Different groups attempted to reduce metabolic cost with exoskeletons but none could achieve a reduction beyond the level of walking without exoskeleton, possibly because there is no consensus on the optimal actuation timing. The main research question of our study was whether it is possible to obtain a higher reduction in metabolic cost by tuning the actuation timing.”
Load cells in exoskeletons
The energy used for this is crucial in the use of exoskeletons to assist in the mobility for the aged, as well as the carrying of heavy loads. It was therefore crucial to accurately measure the action of the pneumatic ‘muscles’ in the exoskeleton, which is where load cells came into play. “We measured the tensile force of the pneumatic muscles at a rate of 1000 Hz by means of a load cell and filtered it with a fourth order Butterworth lowpass filter with a 12 Hz cutoff frequency. Actuation onset was defined as the instant when the pneumatic valve was open and pneumatic muscle force exceeded a threshold of 5 N.”
The team used multiple measurement devices to record the results, including a motion capture system, and respiratory gasses analysis to assess the energy expended. The team concluded that:
“It is theoretically possible to build future ambulant exoskeletons that reduce metabolic cost, without power supply restrictions.”
