  abstract = {Surgical resection of brain tumours is a difficult task. To enhance
	surgery results, a tactile sensor is wanted that gives better resolution
	and sensitivity than the human tactile sense. The characteristics
	of resonant vibrating piezoelectric elements change with varying
	load. This allows for calculation of mechanical load parameters by
	measuring electrical quantities. Different setups of piezoelectric
	sensors have been used to investigate soft materials. Finally, a
	piezoelectric bimorph sensor gave good results for distinguishing
	tissue mimicking gel-phantoms with different gelatine concentrations.
