The present paper presents a finite element model and analysis for the interaction between a piezoresistive tactile sensor and biological tissues. The tactile sensor is proposed for use in minimally invasive surgery to deliver tactile information of biological tissues to surgeons. The proposed sensor measures the relative hardness of soft contact objects as well as the contact force. Silicone r...

We present the concept and results of an investigation all-optical vector-magnetic-field sensor scheme developed for biological applications such as nonzero-field magnetoencephalography magnetocardiography. The differs from classical two-beam Bell-Bloom in that detecting laser beam is split into two beams, which are introduced cell orthogonal directions, ratio amplitudes magnetic resonance sign...
