Wireless Precise Manipulation of Tumor Spheroids Using a Millirobot Controlled by Permanent Magnetic Traps

Advanced Robotics Research, EarlyView.
A magnetic donut‐like millirobot is developed for label‐free pick‐and‐place of a tumor spheroid wirelessly controlled by a magnetic trap. Spheroids are important 3D multicellular culture systems that recapitulate key structural and functional features of native tissues.

Force–Displacement Characterization of PNIPAM Microactuators

Advanced Robotics Research, EarlyView.
A method to experimentally establish a force–displacement diagram of poly(N‐isopropyl acrylamide) (PNIPAM) microactuators, printed by 2PP, is presented herein. PNIPAM is a hydrogel whose volume and stiffness change with temperature due to the absorption or release of water.

Endovascular Microrobotics for Neurointervention

Annual Review of Control, Robotics, and Autonomous Systems
Endovascular techniques have revolutionized the treatment of cerebrovascular disease in the human brain. In this review, we examine the current state of this technology, which consists of multiple concentric catheters that are manually navigated from the lumen of peripheral arterial access within the patient's arm or leg up into the brain using ...
