CamNtech is a specialty medical device manufacturer based in Cambridge, UK. Our products offer innovative solutions for sensing and measurement of human physiological signals and waveforms. The Actiheart is the only validated one piece device on the market which records heart rate and movement and uses these to calculate activity energy expenditure (AEE). It can also be used to record heart rate variability data (IBI) for up to 3 days. The Actiwave family of recorders provide convenient measurements of ECG, EEG, and EMG waveforms. The new MotionWatch 8 was introduced this year as most advance actigraph on the market. Light weight & waterproof are just two of the added benefits of this device.
