Visualize Arrhythmia, Autonomic Nervous System, Stress, etc. with Smartphone Camera! Next-Generation Health Management SaaS "wellmirAi" Enables Prevention of Future Risks for Companies and Employees with 1 Minute of Self-Check Per Day

Femshin Inc. (Location: Roppongi, Minato-ku, Tokyo; Representative Director: Jiro Kanekuni) offers "wellmirAi (Wellmirai)", an AI wellness care SaaS for corporations that enables self-checks by measuring and visualizing signs of arrhythmia, autonomic nervous system balance, and stress levels daily in just one minute using only a smartphone camera.

wellmirAi (Wellmirai) eliminates the need for wearable devices. Using non-contact rPPG technology and patent-pending AI solutions, it accurately estimates heart rate and heart rate variability (HRV), allowing daily changes in physical condition to be treated as management data.

Verification has confirmed an accuracy of 90-97% in heart rate and HRV estimation using rPPG. By improving awareness and accuracy in daily health monitoring, it supports early responses to poor health, sudden death, gender-specific conditions, heatstroke prevention, presenteeism, and risks of labor-related turnover.

Challenges Faced by Japanese Companies

Companies must address more than just sick leave.

Presenteeism, where employees are at work but cannot perform at their full capacity, is estimated to cause losses of approximately 7 trillion yen annually across Japan, expanding its impact on management as an invisible loss.

Furthermore, sudden deaths among the working-age population are estimated at around 79,000 people annually, with reports indicating that over 200 people, or one person every 7 minutes, lose their lives each day.

These health risks are not merely individual employee issues but are human capital risks directly linked to industrial accidents, duty of care, recruitment costs, turnover costs, heatstroke countermeasures, productivity loss, labor management, and presenteeism.

Features of wellmirAi (Wellmirai)

wellmirAi (Wellmirai) is a corporate application that does not require wearable devices like smartwatches. By simply taking a facial photo for about 30 seconds with your smartphone camera, you can visualize the following indicators in about one minute, including a questionnaire, anytime and anywhere. This allows for quick implementation and immediate use in various settings with minimal increase in workload for HR and general affairs.

What wellmirAi (Wellmirai) Can Measure:

- Autonomic Nervous System Measurement

- Arrhythmia Risk

- Heart Rate Variability

- Heart Rate

- Stress Index

- Respiratory Rate

And more

Measurement data is accumulated daily and can be used for continuous health management, including visualization of individual health conditions, AI-driven improvement advice, and correlation analysis with barometric pressure and weather. Additionally, with unique functions that capture gender-specific health conditions through proprietary scores, future predictions, and personalized AI advice, it aims to create opportunities for behavioral change. The target audience includes individuals who are generally less health-conscious, those who lack exercise, and modern individuals who tend to accumulate stress in daily life.

Core Technology

The core technology is rPPG (remote Photoplethysmography).

rPPG is a technology that captures subtle color changes on the skin surface with a camera to estimate pulse waves without contact. Compared to contact devices like fingertip sensors or electrocardiograms, its ease of use with a smartphone makes it highly suitable for daily operation.

wellmirAi (Wellmirai) enhances this technology by combining it with proprietary AI-based correction, achieving practical accuracy suitable for daily use.

Our company is filing a patent application for a proprietary algorithm that combines weather/barometric pressure data, questionnaire results, and gender-specific factors. By capturing the day's condition from multiple perspectives using only a smartphone, not just simple pulse measurement, we differentiate ourselves from other rPPG solutions.

Application for Heatstroke Prevention

Starting June 2025, in environments where the WBGT is 28 degrees Celsius or higher, or the temperature is 31 degrees Celsius or higher, and work is expected to exceed 1 continuous hour or 4 hours per day, heatstroke countermeasures in the workplace have become mandatory. The requirements include establishing an early detection system, preparing procedural manuals, and conducting dissemination and education.

However, even with increased understanding of the regulations, early detection and communication systems in the field are still not fully implemented.

wellmirAi (Wellmirai) can also be integrated with proprietary surveys to support heatstroke countermeasures at the operational level through four steps:

Detect: Early detection of heat stress risk and worker condition.

Alert: Immediate notification of abnormal signs.

Report: Support for reporting systems and response logs.

Act: Assistance in decisions regarding work cessation, cooling, and transport.

This approach addresses not only the heat itself but also the increased risk of severe illness due to combined factors such as arrhythmia, lack of sleep, fatigue, stress, and autonomic nervous system imbalance. Daily visualization of physical condition in the morning serves as the starting point for prevention.

For individuals diagnosed with medical conditions, wellmirAi (Wellmirai) will also collaborate with the MOTHER Bracelet (Mother Bracelet) from Medilom, a Nasdaq-listed company, to further enhance heatstroke prevention efforts and provide safety and security. This collaboration will allow for more effective prevention by collecting daily data.

In-Company Operations

wellmirAi (Wellmirai) is designed for integration into corporate response workflows, not just as a measurement tool. Alert levels are categorized into three stages: Caution, Requires Action, and Emergency, with coordinated responses involving the individual, their supervisor, HR, occupational health, and medical institutions.

It standardizes the entire process, from avoiding hazardous work and determining fitness for duty to continuous measurement for recurrence prevention. The speed of the initial response is key to preventing severe illness and mitigating losses.

Health Management Support

wellmirAi (Wellmirai) goes beyond visualization to support the execution of health management initiatives. It integrates analysis of stress trends and health risks by department, reports for management, design of improvement measures, and operational support.

Furthermore, it offers measures to enhance human capital, such as communication training, mental health training, career support, and AI utilization training. By not just "seeing" health information but also "acting" on it, it aims to improve organizational productivity.

Implementation Effects

Projected effects from implementing wellmirAi (Wellmirai) include reductions in presenteeism losses, compression of absence costs, prevention of turnover, and mitigation of heatstroke response risks.

The investment is estimated at several hundred yen per person per month, with the potential for early recovery depending on operational design.

It also offers the possibility of significantly compressing the management impact by combining losses from minor health issues during normal times with losses from severe work absences. This is not merely a welfare benefit but a preventive investment to protect human capital.

Track Record and Partnerships

In Company A, which implemented the system, particularly among female employees, a 2% decrease in turnover rate, a 15% improvement in operational efficiency, enhanced communication, and increased employee satisfaction were observed over a six-month tracking period. Furthermore, a partnership with is decided, aiming for more advanced vitality management through integration with activity and sleep data. In the future, we plan to expand the implementation of health management by collaborating with local governments and regional companies.

Implementation Flow

Inquiry → Consultation → Contract → Implementation Meeting → Company Implementation Start → Continuous Support

Even after implementation, a team of experts including doctors, nurses, certified psychologists, and HR/labor specialists provides operational support. By accompanying the process until it becomes established in the workplace, we maximize the implementation effects.
