Our Story
Larry Langdon, Founder of Sentient Element has 30+ years of experience
In 2000, Larry was bitten by a tick while hiking in the Cascade foothills east of Seattle. Over time, he experienced persistent health challenges that led him to explore a wide range of approaches focused on supporting overall well-being. Conventional options provided limited long-term improvement, prompting Larry to take a deeper interest in emerging areas of nutrition science and non-invasive, energy-based technologies.
While attending a small, invitation-only seminar on food science, nutrition, and energy medicine, Larry was introduced to PEMF (Pulsed Electromagnetic Field) technology. During a demonstration of a PEMF system operating across multiple frequency ranges, he observed clear physiological responses. Although the experience was intense, it reinforced his interest in how carefully controlled electromagnetic stimulation can interact with biological systems. He left the seminar motivated to understand how such technology could be engineered with greater precision, control, and consistency.
Drawing on his formal training in electrical engineering and decades of experience in software and hardware development, Larry began designing and testing his own electromagnetic coil systems. Early prototypes were inspired by experimental coil architectures, including designs commonly referred to as Doug Coil–style systems, but were re-engineered with a focus on safety, repeatability, and modern control methods. This work led to the development of the Ampcoil, an independently engineered system emphasizing disciplined design, programmability, and non-invasive operation.
Larry’s continued research and engineering efforts expanded beyond a single device, evolving toward a more adaptable and integrated platform. That progression ultimately resulted in the creation of Sentient Element—a system designed to deliver controlled, low-frequency electromagnetic stimulation intended to support general wellness and recovery as part of a broader lifestyle approach.
Larry’s professional background includes advanced engineering work for organizations such as Boeing, National Semiconductor, Intel, Microsoft, and classified programs requiring high-level security clearance. His experience spans hardware and software design, embedded systems, instrumentation, system integration, and product testing, including contributions to early life-support and cardiac technologies cleared for clinical use.
Sentient Element reflects the convergence of this engineering expertise and a long-standing commitment to developing thoughtfully designed, non-invasive wellness technology suitable for consistent use in both home and professional environments.
