The Types taxonomy classifies products by intervention depth, not user goal. Wearable Devices dominate unit shipments, yet their per-device margin compresses as optical sensors commoditize; differentiation now hinges on algorithmic analytics layered atop heart-rate, HRV and core-temperature streams. Implantable & Invasive Sensors sit at the opposite end: although volumes are low, ASPs exceed USD 1,200 because insertion kits require sterile disposables plus clinician training; growth is gated by regulatory burden and athlete apprehension about bans. Nutrigenomics & Supplementation occupy a middle groundโformulation IP underpins 55% gross margin, but efficacy claims are increasingly scrutinised, pushing vendors toward SNP-based personalisation to sustain premium pricing. Neural Stimulation & Cognitive Training tools (tDCS, neurofeedback VR) remain experimental, with revenues booked mainly via university and special-forces pilots. Finally, Software & Analytics Platforms monetise the data exhaust created by all other types; their share of wallet rises when federations mandate centralised athlete-management systems, making software the quiet value aggregator within the Sports and Fitness Biohacking market taxonomy.
