  text: 'In neurosurgery, delineation of tumor boundaries during resection of brain
    tumors is of substantial relevance. During operation distinction between tumor
    and healthy tissue rely on the abilities of the surgeon based on visual and tactile
    differentiation. In this paper a high sensitivity actuator-sensor system using
    a piezoelectric bimorph is presented. Frequency shift and transfer function of
    the bimorphpsilas voltages are detected and evaluated. Sensorpsilas sensitivity
    is evaluated using two frequency controls strategies: A phase-locked loop (PLL)
    and a self-oscillating circuit. Results of measurements conducted on gel-phantoms
    are presented and discussed.'
