TAOS

What TAOS does

TAOS Institute, Inc. (株式会社TAOS研究所) is a Yokohama, Japan-based R&D firm founded in 2012 through the spin-off of the chaos complexity division of CCI Co., Ltd. The company commercializes proprietary algorithms applying chaos theory and nonlinear dynamics to biosignals, including pulse wave (photoplethysmography) chaos analysis, Lyapunov exponent calculation, fractal dimension analysis, multi-fractal analysis (DFA), and unstable periodic orbit (UPO) decomposition. Its product portfolio comprises pulse wave measurement devices (BACS Advance, BAX Detector, Vital Brain/Dr.WAVE), the AiSleep under-mattress sleep monitoring system with smartphone alerts, an IoT-equipped healthcare toilet seat for ECG and HRV capture, an autonomic nervous system analyzer, and a multi-joint coordination analysis system (ESA), supported by an IPA-certified software suite for chaos, wavelet, and neural network analysis.

TAOS sells hardware and software directly to healthcare facilities, care homes, universities, and medical research institutions, with multi-year enterprise contracts and pricing available only on inquiry. A second revenue stream is technology licensing to OEMs, most notably Mitsubishi Electric for the Emoco-i vital and emotion estimation feature in the Kirigamine Z Series air conditioner, which represents a B2B2C channel. The company also conducts joint research with 30+ Japanese universities including University of Electro-Communications, Toyama University, University of Tsukuba, and Nara Prefectural University, supplemented by government grants from JETRO, Yokohama City, Kanagawa Prefecture, METI Kanto, and the Ministry of Health, Labour and Welfare. Customer segments span healthcare and elderly care (primary), academic medical research (primary), automotive driver monitoring (Nissan, Toyota/Hino), industrial predictive maintenance, and consumer electronics OEM licensing.

Core offering

TAOS develops and sells biosignal measurement devices and chaos-based analytical software for healthcare, research, and industrial applications. Its product lineup includes the BACS Advance pulse wave analyzer, AiSleep sleep monitoring system, Vital Brain EEG device, and IoT-integrated health-monitoring toilet seats. The company licenses proprietary chaos-complexity algorithms for stress, fatigue, and sleep-state analysis across automotive, semiconductor, and medical research sectors.

Product overview

TAOS Institute develops a comprehensive health monitoring and chaos analysis ecosystem consisting of hardware sensor devices and software analysis programs. The hardware portfolio includes pulse wave measurement devices (BACS series, Vital Brain), AI/IoT monitoring systems (AiSleep, IoT healthcare toilet seat), autonomic nervous system analyzers (ANS Analyzer), and multi-joint coordination analysis systems (ESA). The software portfolio centers on the IPA-certified Chaos Complex System Analysis Program as the core platform, supplemented by specialized modules for image fractal analysis (FLANA), unstable orbit analysis (UPO), chaos neural networks, mono-multifractal analysis, wavelet analysis, constructive simulation, and surrogate data creation. The company's core technology applies chaos theory to extract subtle fluctuation patterns from biological signals (pulse waves, EEG, respiration) for health prediction, anomaly detection, and autonomous monitoring.

Scale indicators5 records

Expansion highlights5 records

Direct peers

• Empatica: Empatica builds wearable biosensors (e.g., Embrace) that analyze pulse, motion, and electrodermal signals for health and seizure monitoring, with FDA-cleared indications. TAOS's pulse-wave, EEG, and sleep monitoring products compete for the same wearable biosignal-analytics value proposition in healthcare and research markets.
• EarlySense: EarlySense markets under-mattress contact-free patient monitoring for hospitals and elderly care, detecting heart rate, respiration, and motion for fall risk and deterioration. This is the most direct functional competitor to TAOS's AiSleep, addressing the same care-facility and elderly-monitoring use cases.
• Withings: Withings produces connected consumer health devices including pulse-wave, ECG, sleep, and blood-pressure monitors (BPM Core, Sleep Analyzer). TAOS's BACS Advance and pulse-wave chaos analysis compete for the same at-home cardiovascular/sleep health-monitoring buyer.
• Oura: Oura's smart ring combines heart rate, HRV, sleep, and temperature biosignal monitoring with a software analytics platform. TAOS's AiSleep and Vital Brain pursue a similar sleep/recovery-and-vitals analytics proposition with proprietary biosignal processing, making Oura a directly comparable consumer health analytics peer.

Broad incumbents

• Omron Healthcare: Omron Healthcare is an established incumbent in blood-pressure monitors, ECG, and cardiovascular home-health devices. Its cardiovascular and home-monitoring portfolio competes broadly with TAOS's pulse-wave (BACS Advance) and ECG-enabled toilet-seat products, though Omron is not focused on chaos-theory analytical methods.
• ResMed: ResMed is a global leader in sleep-disordered breathing and sleep health, offering connected CPAP and patient monitoring solutions. It addresses the same elderly and care-facility sleep-monitoring use cases as AiSleep but as part of a broader respiratory-focused portfolio.

Regional players

• Sleep Number: Sleep Number's 360 smart bed integrates biometric sleep tracking and adjustable firmness. It is a comparable smart-sleep product concept to TAOS's AiSleep, primarily serving North American consumers through retail rather than Japanese care facilities.

Emerging players

• NeuroSky: NeuroSky builds consumer-grade EEG biosignal sensors and analytics for brain-computer interface and wellness applications, comparable to TAOS's Vital Brain EEG monitor. It is a smaller-scale emerging player with overlapping biosignal-processing technology rather than a head-to-head commercial competitor.
• CASIO (Healthcare / Watch divisions): CASIO has historically commercialized consumer-grade watches with pulse-wave sensing technology, comparable to TAOS's BACS-style fingertip pulse wave devices. It is an adjacent Japanese consumer-electronics player with overlapping biosignal technology rather than a direct competitor in care-facility monitoring.

Others

• WinTest: WinTest is a Japanese sensor/IC company that is a TAOS co-development partner on the IoT healthcare toilet seat. It is not a competitor but an ecosystem collaborator in the Japanese biosignal hardware value chain.
