Background

Wang Dali built his career in hardware engineering after studying mechatronics at Zhejiang University. He describes himself as a hands-on engineer rather than a pure researcher and had worked in the field for more than a decade before finding his place at Sanqing. 577

Lu Tingfeng recruited him during the founding of Sanqing’s medical-equipment department. By the time Sanqing began supplying military medical equipment, Wang was serving as Hardware Development Technology Manager and had become one of Lu’s most trusted subordinates. 428 484

A military live-fire medical exercise broadened Wang’s understanding of battlefield medicine. Working alongside Lu Tingfeng, he observed the need for rapid diagnostics, treatment, and evacuation close to the front line; this experience informed Sanqing’s Military Medical All-in-One Machine and its later airborne application. 419 427

Personality

Wang Dali is relaxed, humorous, and openly fond of taking it easy, earning the company-wide nickname “King of Slacking.” His casual demeanor includes drinking soy milk at his desk, joking with superiors, and treating work banter lightly. 484 573 593

That reputation masks intense focus when he faces a difficult technical problem. Lu Tingfeng considers him reliable on crucial assignments: once engaged by a challenging project, Wang concentrates on solving it and does not drop the ball. 484

He is enthusiastic about practical engineering that can materially improve patients’ lives. His work with paraplegic patients leads him to favor attainable improvements to independence and quality of life over promises of complete recovery that current technology cannot deliver. 572 573

Abilities & Skills

Medical-Device Engineering

Wang specializes in turning technical concepts into functional medical hardware, from diagnostic devices to surgical systems.

• Led development and sample assembly for Sanqing’s endoscope project, including preliminary CMOS-chip testing. 484
• Rejected lowering medical-grade chip standards despite a 50% yield rate, proposing instead that substandard chips be used in mid- and low-end products to improve utilization without compromising high-end equipment. 485
• Proposed Sanqing’s minimally invasive surgery integration plan, combining endoscopes, insufflators, and ultrasonic scalpels into a complete solution; Wei Kang granted him full authority over the project. 485
• Worked with the China Steel Research Institute to secure production of an advanced magnetostrictive material for Sanqing’s ultrasonic scalpel. 486

Ultrasonic Scalpel Development

Wang helped develop and test an ultrasonic scalpel using a magnetostrictive transducer and titanium-alloy blade head.

• Identified that mismatched blade and power-supply frequencies caused internal energy loss, handle overheating, and reduced surgical quality. 487
• Demonstrated the scalpel’s ability to separate meat and fascia rapidly and precisely without overheating during extended use. 487
• Tested the scalpel’s bone-cutting and crushing capability for Wei Kang. 490

Artificial Heart Development

After a year of work, Wang led the development of Sanqing’s third-generation permanent total artificial-heart sample.

• Produced a 90.16-gram artificial heart designed for wireless charging. 560
• Connected the device to a heart model and artificial blood vessels to demonstrate circulation before animal testing. 560
• Oversaw a successful pig heart-transplant experiment at the Kunshi City Animal Experiment Center. 561
• Acknowledged remaining barriers before clinical use, including immune response, thrombosis, hemolysis, infection, and power supply. 560

Brain-Computer Interfaces and Bionics

Wang collaborates with Chen Yiqing on devices intended to restore autonomy to paralyzed patients.

• Developed a mouth-controlled device mounted on modified glasses, enabling Zhu Jun to control functions by biting, blowing, or sucking on a rod near his mouth. 572
• Joined Chen Yiqing’s semi-invasive brain-computer-interface project as the engineer responsible for external motor signals and mechanical systems. 573 574
• Designed a cerebral vascular stent for the brain-computer-interface project. 577
• Guided Zhu Jun through thought-controlled computer operation, including mouse use, browsing, and other basic actions. 582
• Explained Zhu Jun’s rapid gaming improvement as adaptation to the interface’s low-latency control. 583

Bionic Prosthetic Limbs

Wang applied surgical-robot technology to make bionic prosthetics more dexterous and useful.

• Designed mechanical blueprints around thirteen basic hand movements, including gripping, pinching, pushing, striking, and multi-finger manipulation. 606
• Developed flexible nano-metal electrode needles for connecting a bionic hand to the median, ulnar, and radial nerves; the material is painless, biocompatible, and intended to avoid rejection or infection. 608
• Personally tested the bionic hand’s movement and sensory feedback, including pressure, temperature, touch, and motion perception. 608
• Helped demonstrate the prototype’s daily-use functions with amputee Tang Jian, who used it for gripping, pinching, lifting, and typing. 609
• Supported Wei Kang’s plan for long-term installment payments to make bionic prosthetics more accessible to disabled users. 612

Surgical Robotics

As Robot Laboratory director, Wang leads Sanqing’s effort to challenge the Da Vinci surgical robot with the semi-automatic multifunctional surgical robot Miao Shou.

• Accepted responsibility for developing a more affordable surgical robot despite Da Vinci’s market dominance. 594
• Led the first prototype’s testing, operating its robotic arms to peel grapes in seconds. 645
• Described the controls as feeling like additional, highly flexible hands capable of movements impossible for ordinary human hands. 645
• Oversaw demonstrations of fine robotic suturing on grape skin and raw egg membrane. 645

Relationships

• Lu Tingfeng — Former supervisor and mentor who recruited Wang into the equipment department, delegated major responsibilities to him, and trusted his ability to handle difficult technical projects. 428 484 560
• Wei Kang — President of Sanqing and Wang’s principal patron. Wei repeatedly recognizes Wang’s contributions, grants him project authority, and appoints him to lead the Robot Laboratory. 485 490 593 594
• Chen Yiqing — Neuroscience collaborator and mentor-like partner on brain-computer interfaces and bionic limbs. Chen values Wang as the engineer capable of materializing his ideas. 573 574 608
• Zhu Jun — Paraplegic patient and collaborator. Wang created Zhu’s mouth-control device, recruited him for brain-computer-interface trials, and guided his thought-controlled computer training. 572 574 582
• Wenren Long — Colleague and fellow brain-computer-interface researcher. Wang frequently trades jokes with him and volunteers him for later bionic-hand testing. 573 580 608

“Use me ruthlessly, use me to death, I can definitely handle it!” 573

“The people I choose will never be wrong.” 582

“This is the ideal life for a tech mogul.” 487

Trivia

• Wang is health-conscious and maintains what he considers a robust physique through attention to health and wellness. 345
• He once carried a delicate bionic mechanical arm to testing in a plastic bag, considering formal packaging unnecessary for an internal experiment. 608
• During ultrasonic-scalpel testing, Wang’s team used the processed lamb leg for a barbecue. 487
