  100+ Motion Parameters. From the Head. Most wearables track movement. BiomechEngine analyzes it. While typical devices focus on steps and pace, BiomechEngine delivers  100+ advanced motion parameters in real time  — including metrics traditionally limited to laboratory environments. At the center of it all: the head. Beyond Steps: 100+ Advanced Motion Metrics BiomechEngine provides real-time access to: Cadence Vertical Oscillation Head Angle Left–Right Balance Step Width Impact Shock Single-Leg Support Time Double Support Time Flight Time Ground Contact Time And advanced Ground Reaction Force (GRF)-related indicators This isn’t surface-level tracking. It’s full-spectrum biomechanical insight. The system goes beyond counting movement and begins interpreting mechanical behavior — including parameters typically associated with force plates and motion labs. Why Head-Based Measurement Changes Everything The comparison is simple. Metric Head (BiomechEngine) Waist Pods Smartwa...

 For years, wearable technology has focused on visibility. Steps. Calories. Heart rate rings. Activity badges. But the next wave of innovation is moving in the opposite direction. It’s becoming invisible. BiomechEngine sits right at the center of this shift. From Quantified Self to Interpreted Self The first era of wearables was about counting. How many steps? How many minutes active? How many calories burned? The second era is about interpretation. Not just: “Did you move?” But: “How did you move?” “Was it efficient?” “Was it stable?” “Did it change over time?” BiomechEngine aligns with this evolution — transforming raw motion signals into meaningful movement patterns. Why Movement Quality Is Becoming Important In sports science, movement quality has always mattered more than movement quantity. Two runners can: Run the same pace Cover the same distance Burn the same calories Yet one may: Experience less impact stress Maintain better balance Show more mechanical efficiency And over...

  Is the Wrist Still the Best Place to Measure Human Movement? For over a decade, the smartwatch has been the center of wearable fitness. It tracks: Steps Distance Pace Heart rate Calories But as wearable technology evolves, a new question is emerging: Is the wrist really the best place to understand how humans move? BiomechEngine proposes a different answer. 1. Sensor Location: Wrist vs. Head Smartwatch: The Moving Target The wrist is highly mobile. It swings during walking. It rotates independently of the torso. It moves differently depending on arm style. Two runners with identical lower-body mechanics can produce very different wrist data simply due to arm swing differences. This makes wrist data excellent for activity detection — but less ideal for detailed movement quality analysis. BiomechEngine: The Central Anchor Ear-worn devices sit at the head — one of the most stable and centrally controlled segments of the body. The head reflects: Whole-body balance Vertical displaceme...

  Turning Everyday Earbuds into a Motion Intelligence Platform What if the device already in your ears could understand how you move? BiomechEngine is built around a simple but powerful idea: head-worn wearables are an untapped biomechanical goldmine. Instead of adding more hardware to the body, BiomechEngine leverages sensors inside everyday earbuds and transforms them into a real-time movement intelligence system. No straps. No lab setup. No camera rig. Just motion — decoded. Why the Head Matters More Than You Think Most consumer fitness tracking today happens at the wrist. But the wrist swings. It rotates. It exaggerates motion. The head, on the other hand, behaves differently. In biomechanics research, head stability is closely tied to: Balance control Gait symmetry Neuromuscular coordination Fatigue patterns The head reflects whole-body movement in a more centralized, stabilized way. That makes it a surprisingly powerful observation point. BiomechEngine builds on this concept....

  Every step you take has two phases: Contact Flight Performance is largely determined by what happens during contact. StrideCoach measures  Ground Contact Time (GCT)  using  BiomechEngine™, developed by Beflex’s biomechanics research team , extracting stance-phase timing from head-based motion data captured by AirPods. What Is Ground Contact Time? 4 Ground Contact Time is the duration your foot remains on the ground during each stride. Recreational runners (easy pace): ~250–320 ms Competitive runners: Often <250 ms (pace dependent) Sprinters: Even shorter contact times Shorter contact does not automatically mean better — but it reflects how force is applied. Why GCT Matters Ground Contact Time influences: Elastic energy return Running economy Speed production Research Evidence Weyand et al., 2000  – Faster runners generate greater forces in shorter contact times. Barnes & Kilding, 2015  – Contact time associated with running economy and performance....

  Running is forward motion. But many runners move excessively upward. That vertical movement costs energy. StrideCoach measures  Vertical Oscillation using BiomechEngine™, developed by Beflex’s biomechanics research team , analyzing head-based motion patterns captured by AirPods. What Is Vertical Oscillation? 4 Vertical Oscillation refers to the amount your body moves up and down with each stride. Some vertical movement is necessary. Excessive vertical displacement: Increases metabolic cost Reduces forward efficiency Accelerates fatigue You are spending energy lifting your body instead of propelling it forward. Why It Matters Running economy — the oxygen cost at a given speed — is strongly influenced by mechanical efficiency. Research Evidence Saunders et al., 2004  – Running economy influenced by vertical displacement efficiency. Moore, 2016  – Lower vertical oscillation associated with improved running economy. Williams & Cavanagh, 1987  – Efficient runne...
