Abstract: A system and method for determining position of a steerable assembly within tissue of an animal body utilizes an elongated body structure with an implement arranged at a distal end thereof, and a premagnetized material proximate to the distal end. A signal indicative of a length of insertion of the elongated body structure into the tissue is used with a signal indicative of (i) force, strain, shape of a sensor associated with the elongated body structure and/or (ii) directionality of magnetic field applied to the premagnetized material, to determine a three-dimensional (3D) trajectory of the steerable assembly. The 3D trajectory is superimposed on a 3D model of the tissue to determine position of the steerable assembly within the tissue.

Abstract: Tunable electronic units and associated systems, as well as methods for tuning characteristic properties of soft electronic units (e.g., inductance, capacitance, and resistance) and fabricating soft tunable planar inductors, axial inductors, capacitors, and resistors, are provided. Disclosed systems and methods enable standardized tuning of different types of soft electronic units (e.g., including a soft inductor, capacitor, and resistor, etc.), and enable remote tuning while maintaining a tuned value without expending power. In certain embodiments, electrical properties of the soft electronic units are tuned using a mobile component (e.g., ferrofluid and iron powder) dragged with a permanent magnet inside a soft fluidic channel. This may be used for applications and devices which need to be soft and flexible, such as implantable electronics, wearable devices, and skin electronics.

Abstract: A steerable assembly comprises an elongated body structure with an implement arranged at a distal end thereof, wherein a premagnetized material is arranged closer to the distal end than a proximal end, and is configured to enable steering of the implement through tissue of an animal body responsive to application of a magnetic field eternal to the body. A method for guiding passage of an implement through tissue includes altering strength and/or position of at least one magnetic field source external to an animal body to interact with and effectuate movement of a premagnetized material inserted into the animal body.

Abstract: An electromagnetically actuated robotic device comprises electromagnetic coils, a charge storage element, at least one processor, a plurality of electrically conductive paths, optionally in combination with sensor(s), all arranged in, and/or on, an elastomeric body structure. Shape, gait, and/or electrical properties shape of a robotic device may be altered by selective actuation of one or more electromagnetic coils.
