A medical lab on your wrist

DEEP INFRARED wearable sensor for continuous monitoring of physiological parameters in the body


We are an Israeli start-up, leading the next era of smart-wearable devices.

Our technology enables to place a medical lab on every person's wrist for personal up-to-date physiological state monitoring.

Our DEEP INFRARED sensor provides personal physiological data monitoring which is essential for supporting our fitness and health activities, as well as alerting when a significant medical condition is taking place.

Our wearable DEEP INFRARED sensor makes the power of medical lab accessible by placing it on each person's wrist.


Our main application is a proprietary DEEP INFRARED wearable sensor for monitoring Lactate levels in the blood.


In real-time


A direct measurement of Lactate

Our technology will evolve to monitoring additional molecules in the body which has a significant medical value.



Today's wearable health applications are based on sensors which exists for over 20 years:
Oximeter (heart-rate), GPS, Accelerometer, ECG (EKG).
These sensors are limited in providing extensive physiological data.
The common electro-optical sensor today, the PPG (Oximeter, heart-rate sensor on today's smart wearable devices) is not capable to emit in DEEP INFRARED wavelength and therefore not capable of providing significant medical data.
Most of the significant molecule data can be recognized only in DEEP INFRARED wavelength range.
That is why significant physiological parameters measurement is done mainly with invasive devices under medical environment and therefore not accessible for daily use.
Invasive measurements do not provide real-time parameters monitoring, therefore lack of providing the molecules concentration trend.

Our sensor will be implemented into smart wearable watch / bracelet / band.



The generic marker of the medical world

We are monitoring the change of Lactate concentration in the body.

A person usually has a 1.2-1.4 mmol/L Lactate concentration in the body.

Lactate concentration may raise mainly due to two conditions:

  1. A severe medical condition.

  2. While performing a too intense fitness activity.

Lactate can be optically recognized only in DEEP INFRARED wavelength.



Lactate is the main generic marker for development and treatment of medical shock situations.

The Lactate concentration changes in the body is the main indicator for severe medical conditions such as:


Septic shock


Liver disease

Cardiac disease


And more...

Our sensor will alert when Lactate concentration raises.

The wearable device will share the data with the relevant medical team, so they will be ready to perform the right treatment immediately when the patient arrives to the emergency room, instead of waiting to hospital lab results.



Lactate monitoring is the target for early resuscitation in sepsis

Sepsis is the body’s overwhelming and life-threatening response to infection that can lead to tissue damage, organ failure, and death.

In other words, it’s your body’s overactive and toxic response to an infection.

Fast identification and reaction is crucial since the patient might have no more than 12-24 hours to survive.

Once our Lactate concentration raises to around 2.5 mmol/L and above (not due to fitness activity) it means we are probably in a severe medical condition.

the most common critical condition in this case is Sepsis.

With Lactate concentration of 2.5mmol/L we already have a survival rate of only 75%.

As time passes, our chances of surviving decreases dramatically.

Having an early indication of Sepsis followed by fast arrival to the hospital and saving time on diagnostics at the hospital is crucial to the survival of the patient.

It is also important for cost of the treatment.

Here are some important fact about Sepsis:

  • Sepsis affects around 1.5 million individuals in the United States annually. 30 million people worldwide.

  • Causing the death of 250,000 individuals and being responsible for 1 out of every 3 hospital deaths in the US. 6 million deaths worldwide.

  • Sepsis was one of the major risk factors identified that led to in-hospital death, discharge to hospice facilities, or 30-day readmission.

  • It costs less for a hospital to treat sepsis upon admission, at about $22,000 per case compared to $70,000 for hospital-associated sepsis.

  • Average cost per case for hospital-associated sepsis jumped from about $58,000 in October 2015 to about $70,000 in September 2018.

  • The average length of stay (LOS) for septic patients was 75% longer compared to those hospitalized for other conditions, and septic patients were eight times more likely to die during hospitalization.



Lactate Threshold is the golden standard of endurance fitness measurement and is not being monitored today at all.

Lactate threshold is the main parameter for exploring your endurance limits.

Endurance is built out of mental and physiological capabilities.

So even if your mental side tells you to stop, but you haven’t reached lactate threshold, then you still have energy to continue the activity.

Lactate threshold is the only predictor of endurance performance.

It is the best indicator of exercise intensity.

Why do they tell you to not go over heart-rate of 160?

Because you can’t monitor lactate, so heart-rate is used as a rough safety zone to prevent you from reaching Lactate Threshold, but also prevents you from exercising your full performance.



The golden standard of endurance measurement

When your intensity is too high, and you lack of oxygen, Lactate accumulates in the blood.
Eventually  you will reach Lactate Threshold. A point where your brain stop your activity by making you feel bad.
It may take few minutes to reach Lactate Threshold.
It takes from couple of hours and up few days to fully recover.
Our sensor will alert when heading to Lactate Threshold.
You will then adjust to the right intensity, and will conclude the event within optimal performance.
The data collected by the sensor will be used to analyze your training and plan your coming competition.
The sensor is targeted to every level of athletes. From those who starts to train for their first 10K run, and up to professional athletes.



Lactate is measured mainly via invasive devices

Lactate measurement is done mainly by taking a blood sample (from finger or ear knob) and analyzing it with a special device, mainly under lab  environment.

In hospitals, Lactate is measured with the blood analysis procedures.

These methods provide a one point measurement of the time that the blood sample was taken.

It doesn't provide monitoring.

It doesn't provide continuous trend data.




Recognition of Lactate is done by Spectroscopy.
Spectroscopy is used by the standard wearable heart-rate sensor today, but limited to performance in the deep Infrared.
Our technology performs spectroscopy in deep Infrared wavelength region.
The most interesting data on organic molecules is in the deep Infrared.
Current emitting sources (such as LED and others) aren’t common and not effective for accurate detection in deep Infrared.



On December 2018, we've concluded a 3 month program at the leAD Sport Accelerator at Berlin.
leAD was established by the family of Adi Dassler, the founder of Adidas, to revive his innovation spirit by supporting Sport-Tec start-ups.
Over 400 Sport-Tec start-ups from all over the world applied to the 3 month program in Berlin.
25 passed to the selection days.
9 were selected for the program.
We were honored by being one of the selected start-ups to the program and the only one from Israel (out of 15 which applied).
These days we are looking, together with leAD, for an investment which will enable us to go into production of the core technology.
