Challenges and Opportunities in Combining Ultrasound and Inductive Coupling for Energy Supply and Bidirectional Data Exchange in Bioelectronics Medicine Implant Networks

open access: yesAdvanced Intelligent Systems, EarlyView.
In this contribution, it is shown that miniaturized nerve stimulation implants can be used in collaborative networks. Inductive links and ultrasound are combined to supply these implants with energy and data; the advantages and disadvantages of each method, as well as safety risks and possibilities for improvement are discussed and the best ...

Interpolating splines as limits of polynomials

open access: yesLinear Algebra and its Applications, 1983
AbstractLet the points (1)(xi,yi) (i=l,…, k; k⩾2), a⩽x1≤x2≤⋯ ≤xk⩽b, I= [a,b] (−∞≤a≤b≤∞) be prescribed. Furthermore, let m and n be integers such that l⩽n⩽k⩽m, and define the polynomial class Πm={P(x):P(x)επm,P(xi)=yi(i=l,…, k)}. Within Πm we determine Pm(x) as the solution of the extremum problem ∫I[P(n)(x)]2dx=minimum for P(x)εMm.

Robotic Interventional Needle Insertion Assisted by a Cable‐Driven Parallel Robot

open access: yesAdvanced Intelligent Systems, EarlyView.
This article presents a body‐mounted cable‐driven parallel robot assisting the needle insertion procedure designated for automated interventional pain therapy. The 3D‐printed robot body and multiple thin cables can achieve high X‐ray compatibility for intervention. The robot performs full 6‐degree of freedom needle insertion and remote center of motion

Autonomous Sorting of Beads in a 3D Environment Using Levitating Magnetic Microrobots

open access: yesAdvanced Intelligent Systems, EarlyView.
An untethered, magnetically actuated microrobot autonomously collects, weighs, classifies, and sorts passive particles in 3D environments. The system integrates motion control, trajectory planning, and action scheduling to perform fully automated operations.

Is Computing with Light All You Need? A Perspective on Codesign for Optical Artificial Intelligence and Scientific Computing

open access: yesAdvanced Intelligent Systems, EarlyView.
This perspective article considers what computations optical computing can and should enable. Focusing upon free‐space optical computing, it argues that a codesign approach whereby materials, devices, architectures, and algorithms are simultaneously optimized is needed.
