The Moxy Sensor is the heart of the Moxy Monitor System. Its light emitting diodes and photo detectors together create the spectrometer that makes Muscle Oxygen measurement possible. Fully functional and self-contained, the Moxy Sensor has a battery for power, a microprocessor for operating the spectrometer, and a memory chip for storing data; it also has a radio transmitter for sending live data to other devices.

Moxy provides real time physiologic feedback for any sport: it is strong enough to withstand the rigors of motocross riding and rugby; it is secure enough to operate in the swimming pool; it is portable enough to wear on the football field. Moxy takes physiologic monitoring out of the lab and into the real world of sports.

  • Lithium Polymer battery for at least 6 hours of run time and a 2 hour recharge time
  • Data Storage for more than 6 hours of data
  • Wireless charging using the Qi standard
  • ANT+ and BLE Radio for transmitting data to sport watches, smart phones and computers
  • Weighs less than 40 grams (1.4 oz)- Half as much as some sport watches
  • Sealed, water resistant case
  • Two-second data update rate


  • Moxy is so small and light that you forget you’re wearing it
  • Moxy interfaces with many existing devices and software programs that use ANT+ or BLE
  • Internal data recording allows Moxy be used where radio transmission of data is difficult, such as under water
  • Provides real time physiologic feedback
  • The Moxy algorithm is insensitive to motion, so it can be used in even the most vigorous sports
  • Moxy is physiologically accurate; it is designed to measure into muscle tissue through up to 12 mm (1/2”) of fat layer thickness


The Science Behind Moxy

Moxy uses light from the near-infrared wavelength spectrum (light from about 670 to 810 nm) to measure muscle oxygenation levels in muscle tissue. Human tissue has low optical absorbance of near-infrared light, so the light can travel to reasonable depths. The near-infrared wavelength range is particularly useful because hemoglobin and myoglobin change color in that range depending on whether or not they are carrying oxygen. For more details, check out our paper, The Science Behind Moxy.



Peripedal is a PC software developed for indoor cycling that monitors Muscle Oxygen, Heart Rate, Power, and Speed & Cadence data via ANT+. It can also calculate power from the speed data of most available trainers, allowing you to do power-guided workouts without a power meter. Different versions of the software support up to eight simultaneous users. Peripedal also offers integrated video entertainment while you ride.

PerfPRO Studio and Analyzer

PerfPro Studio is a training app designed for the indoor cycling studio.  It interfaces with many common bicycle trainers, including Computrainer and the Wahoo Kickr. PerfPro collects Muscle Oxygen, Heart Rate, Power and Speed & Cadence data from ANT+. The data can be transferred to the PerfPro Analyzer for logging workouts and analyzing performance.


SportTracks is a complete solution for planning, tracking, analyzing, and sharing your workouts. It provides extensive post-workout analysis of Moxy Monitor data, enabling you to directly compare your blood oxygenation levels with your pace, heart rate, and other metrics from the same workout. SportTracks is truly multi-sport. Running, cycling, and swimming are very different activities, and each one is approached uniquely. Athletes love SportTracks for its ease of use, and deep analytical power. The best way to understand it is to experience it yourself.

Garmin ConnectIQ allows customized apps to be run on Garmin watches. There is currently a Moxy Cycling App and a Moxy Running App available on the Garmin App store with more in development. These apps are compatible with the Garmin 920XT, Vivoactive, Fenix3, and Epix watches. Check out our online store for packages that include. The apps allow you to display Moxy data along with your GPS, speed, cadence, heart rate and more. The current Connect IQ platform does not allow recording new sensor data to the FIT file such as the Muscle Oxygen data that the Moxy sensors provides. When this feature is added to the Connect IQ tools Moxy will immediately incorporate it into this app. Include link to pairing video.

IpBike is an app which turns your Android phone into a bike computer. It collects Muscle Oxygen, Heart Rate, Power & Speed & Cadence data from ANT+ and Bluetooth Low Energy (BLE), as well as GPS information. It provides many options for customizing the display to show you the most relevant information while you ride. Android phones such as the Sony Xperia or the Samsung S4 have native ANT+ support (the Sony Xperia is also waterproof). Android phones that do not have native ANT+ can be used with an OTG cable and an ANT+ dongle.

Legacy GPS Sport Watches

Moxy can send data to any sports watch which uses either the Muscle Oxygen or Speed and Cadence ANT+ profile. The Speed and Cadence option allows the Moxy Sensor to use the Speed and Cadence display fields in watches which have not yet implemented the new Muscle Oxygen profile.

Real Track Systems (WIMU PRO and SPRO)

WIMU PRO is a device worn by the athlete to collect movement information with accelerometers and position tracking. WIMU PRO also acts as an ANT+ to Wi-Fi bridge which allows the device to collect data such as Muscle Oxygen and Heart Rate from ANT+ sensors on the body. WIMU PRO sends all collected data over Wi-Fi to the SPRO software, which can synchronize all of the the data along  with video of the workout. This is the perfect system for analysis of athletes in team sports or any type of analysis where you want to collect motion and Muscle Oxygen data at the same time.


ZeroPace is training log software which allows you to import Moxy .CSV files and log the data with other workout data. Useful for keeping track of workouts, the ZeroPace software makes it easy to review your historical data.


Golden Cheetah is a free cycling software. It allows you to record Moxy data in real time over ANT+ or import the .FIT files from multiple sources and combine them into a single analysis. Golden Cheetah can also download data directly from the Moxy sensor.
