World's smallest class wireless electrocardiograph ZMP® ECG 2


This product is compact and lightweight about 15 g and enables wireless measurement.
The sampling rate corresponds to 256 Hz / 204 Hz / 128 Hz / 100 Hz and the 3 axis acceleration sensor and the temperature sensor are carried.
By using a unique communication protocol to reduce power consumption, it is possible to continuously measure approximately 48 hours when measuring all sensor data with a single button battery and approximately 120 hours when measuring only electrocardiogram. Monitoring software is included, attach the electrode to the body, attach it to the chest and start the measurement immediately by pressing the switch. It can be used for applications such as acquiring biological information in the fields of robotics, biomedical engineering and welfare engineering, measuring the electrocardiogram of drivers in the automotive field and measuring health conditions.

· About 15 g (including batteries) and compact, lightweight and wireless. Reduce burden on subjects
. After attaching the electrode and mounting it on the chest as it is, if you press the switch, an electrocardiogram etc is displayed on the personal computer.
· Small but multi functional , high performance (baseline stability , low power consumption , wireless function). Since there is no burden of wearing as its is small, it can be used widely from children to elderly people.

Continuous 72-hour measurement with button battery is possible. Automatic communication recovery function available
Drive continuously for 72 hours with a coin battery (CR 2032) that you can buy at a convenience store.
If sampling is halved (100 Hz) it will continuously drive for about 7 days.

Start attachment by attaching an electrode, attaching to the chest, pushing a switch.
With original protocol development, pairing is minimized with initial setting alone.
Even if the radio waves are cut off, automatic communication recovery function with reliable, timestamp function is carried.
Complex measurement is possible by measuring three axis acceleration and temperature at the same time.

Also equipped with 3 axis acceleration and temperature sensor. Posture and exercise are also telemetered
Heart rate variability analysis is also possible if you use electrocardiogram electrocardiogram analysis software (optional).
Software Development Kit (SDK, sold separately) is also available for developers. You can develop applications with VC ++.

Heart rate variability real time analysis program
It is possible to read the autonomic balance of sympathetic and parasympathetic nerves by analyzing heart rate variability with this program.
The analysis result is updated every 2 seconds. It is also possible to save the analysis result and the collected ECG waveform and reanalyze the same data.
An event mark (number) can be inserted during measurement and it serves as information necessary for inspection and long-term recording.
It is possible to judge the medication effect or the massage effect. It is also applied to inspection of fatigue and stretch.
