Project description
Bite force is a factor that significantly affects feeding and social behaviour in vertebrates. It can be regarded as a performance trait that is directly linked to the evolutionary fitness of an individual (REFS). Within the framework of a joint project, new measurement systems and methods for a quality-assured quantitative determination of biting forces in dogs are to be developed. Due to their great variability in body size and snout geometry, dogs represent model organisms for investigating factors influencing biting force.
As a first prototype, a chasing arm was sensorized by means of load cells, which allows to measure biting forces during an attack bite in high temporal resolution. On the basis of this system, preliminary studies are currently being carried out, which are to serve for the improvement of the sensorised bite arm and the development of further measuring systems.
