France’s space agency CNES with space medicine specialists from MEDES have developed a personal assistant app for astronauts to use via a tablet called EveryWear. The French-designed technology is as simple as a custom application for a tablet that astronauts on board a space station can carry around.

While in space, ESA astronaut Thomas Pesquet, will be the first to test this new way of collecting information during his Proxima mission to the ISS.

The EveryWear system is an ambulatory data collection system making use of wearable sensors connected to a station iPad itself wirelessly synchronized with ground. This easy-use system should demonstrate extensive physiology data collection for both science and medical follow-up purpose by improving usability for the astronauts.

All functions are embedded inside a dedicated custom iPad application.

The experiment hardware consists of the following:
· station iPad (provided by NASA)

· biometric smartshirt
The smartshirt is an intelligent t-shirt allowing the collection of ECG data and actimetry monitoring. ECG sensors are embedded in the garment fibers and activity monitoring is performed via accelerometer in the smarsthirt gateway. During data collection, the crew wears the smartshirt and the gateway is inserted in a small pocket of the smartshirt. The gateway transmits real time data to the iPad application using Bluetooth Low Energy connection. The gateway is powered by a Lithium-Ion battery (3.7V, 320mAh, 1.2Wh) and contains the Bluetooth antenna.

· biometric patch
The Biometric Patch is a wireless sensor allowing assessment of body temperature and levels of physical activity. The sensor is applied on the subject chest or forearm using Medical Tape. The patch contains a Bluetooth antenna to communicate real time data to the iPad application and a soldered rechargeable lithium-ion battery. The Biometric Patch is recharged by the Biometric Patch Base, in which a 9V alkaline battery is inserted. For the full data transfer to the iPad application, the Biometric Patch can be set on the Base and the Base directly connected to the iPad using the lightning port. The cable is soldered to the Biometric Base.

· self-applied tonometer sensor (sponsored by ESA/EAC in collaboration with INSERM)
The Tonometer is a finger worn sensor able to record the pulse wave of the crew member. The recording is done using a piezoelectric technology. During data collection, the Tonometer is connected to the iPad using the lightning port and the data are transmitted to the iPad application. The cable is soldered to the Tonometer.
EveryWear system aims to offer one interface for a variety of health-related tasks - both medical and research. It is evolutionary and can integrate further sensors and functions. It can be used for:
- science experiments,
- biomedical support and
- technology demonstrations.
The application promises to be a huge time-saver as it records and transmits data from as many experiments as possible.
The system can be used for questionnaires, taking medical and clinical logs, monitoring exercise when coupled with the EveryWear Smartshirt and even assess the astronaut’s sleep quality. Presently, if an experiment requires the astronaut to take a log of daily food consumtion the astronaut would need to write down each piece of food ingested throughout the day. With EveryWear, the astronaut can simply take a photo to scan the bar code of a food item before eating - the app will record the calories and provide a nutritional assessment and compare the result with his personal target defined before the flight.

A second use for EveryWear is combining input from three wearable sensors: a tonometer to record how the astronaut’s arteries react to weightlessness; a smart shirt that records his electrocardiogram during exercise and a patch that records the astronaut’s skin temperature to monitor sleep patterns in space.

EveryWear also offers support for experiments, such as AquaPad, that are being tried as a new way to ensure water on the Space Station is not contaminated. During the Proxima mission, ESA astronaut Thomas Pesquet simply took a picture of a specially developed petri-dish where coloured dots would develop as an indicator of bacteria. EveryWear processes the picture to calculate the amount of bacteria in the water – confirming whether it is safe to drink.

Thomas Pesquest was the first astronaut to test the application.

EveryWear is an iPad-based application that collects physiology and medical data from astronauts on the ISS. It is connected to wearable biomedical sensors that record exercise, heart rate and sleep quality. Its main use is as a food diary. The astronaut simply scans the barcode of the food with the built-in tablet camera, classify it as breakfast, lunch dinner or snack, and add how water was consumed. The crew can also add food by tapping on a specific product. The app comes loaded with a database containing all the food on the Space Station, both in English and in Russian. If something is not listed yet, there is an option to take a picture. An added value of the tool is that it connects the astronaut with nutrition experts on Earth, some 400 km below. Ground teams receive the information and can suggest the best combination of meals for a healthy stay in orbit. In addition to the weekly expert advice, the app delivers automated nutrition reports for astronauts to monitor their daily intake and check the recommended dose. The focus is on calories, protein, water, carbohydrates, fat, sodium, calcium, iron and potassium.
