Endovascular, cardiac, orthopedic, dental, and bronchoscopy robots each guide an instrument through a different, delicate path in the body, but all depend on translating a surgeon's hand movement into motion precise enough to work inside confined spaces, filtering out tremor while scaling motion down to a fraction of its original size. Vishay's power MOSFETs support the fast, accurate switching that kind of fine motor control depends on, while current sense resistors feed the real-time feedback loop that helps detect force at the instrument tip.
