Untethered magnetic manipulation of biomedical millirobots has a high potential for minimally invasive surgical applications. However, it is still challenging to exert high actuation forces on the small robots over a large distance. Permanent magnets offer stronger magnetic torques and forces than e
Magnetic helical micro-robots (microbots) have attracted strong interest due to their unique propulsion mechanisms and potential applications in biomedical fields, particularly in minimally-invasive surgical procedures. Earlier research primarily focused on studying helical microbots in viscous liqu
Early detection of gastrointestinal (GI) cancer is critical for improving treatment outcomes and survival rates. Yet conventional endoscopic techniques remain invasive and labor-intensive, thus presenting significant challenges for cancer screening on large populations. Current commercially availabl
Surgical planning and training based on machine learning requires a large amount of 3D anatomical models reconstructed from medical imaging, which is currently one of the major bottlenecks. Obtaining these data from real patients and during surgery is very demanding, if even possible, due to legal,
With early sign of bowel cancer being changes in affected lesions biomechanical properties, an AI-assisted dynamic tissue evaluation is proposed for early bowel cancer diagnosis. Dynamic signals from a self-propelled vibrational capsule in contact with in-situ bowel lesions were processed and analys
Uptake of capsule endoscopy in the large intestine has been very limited due to both the risk of missed lesions and the often prolonged transit time, making it an unviable alternative to standard colonoscopy. In this letter, we presented a controllable and easy-to-use diagnostic tool, equipping a no
This paper presents a novel design and experimental investigation for a self-propelled capsule robot that can be used for painless colonoscopy during a retrograde progression from the patient's rectum. The steerable robot is driven forward and backward via its internal vibration and impact with orie…
