Quality Sensors

Each left and right SCIENCE Sensor Insole contains pressure sensors and a gyroscope sensor. More detailed information can be found in the specifications section below.

16 Pressure Sensors

Sensor insole outline and sensor positions are given in a common coordinate system. The orientation of the coordinate systems is different for left and right sides.

6-Axis Gyroscope

Position of the gyroscope sensor is the origin of the coordinate system. Orientation of coordinate system is different for left and right sides. The sensor data contains 3 dimensions in space for acceleration and angular rate data.

Operation Modes

Standard Modes

Preview

Transmits fixed basic sensor data wirelessly

For activity checks and live showcasing in the Moticon SCIENCE Mobile App

Live

Transmits selected sensor data channels  wirelessly to endpoint (computer/cloud)

Direct data transmission to store on endpoint

Record

On-board sensor data recording

For standalone data acquisition without need for phone/ computer/ cloud

Note

The operation modes Live and Record can be software-selected in the Moticon SCIENCE Mobile App. The Preview mode is always on when connected to a phone. The Transmit mode is activated automatically when data is transmitted.

Intelligence Modes

Smart Recording

Activity triggered recording mode. Recording is only on when users are active. Internal firmware controls start/stop of recording automatically. No phone is required.

For longterm gait monitoring

Smart Sleep

Automatic shut down into power safe mode when sensor insole is not in use. No hardware switches are used.

No user interaction for turning on/off required

Note

Smart Recording is currently undergoing an R&D update from previous sensor insole generation. Estimated availability is 10/2019.

System Functions

Firmware Update

Firmware of the sensor insoles can be updated wirelessly using the Moticon SCIENCE Mobile App.

File Management

Firmware runs a file management system on the on-board memory of the sensor insole. Measurements can be selected, deleted and transmitted individually using the Moticon SCIENCE Mobile App.

System Status

The firmware continuously checks the system status and transmits status information. Status information includes:
1. OK/NOK pressure sensors 1-16
2. Restarts
3. Active time
4. Miscelaneous (firmware version, serial number, size, side)

Battery Status

The firmware detecs the battery charge status of the inserted coin cell batteries. The charge status is transmitted to the Moticon SCIENCE Mobile App.

Wireless

Wireless Standard

Bluetooth Low Energy 5.0

Version refers to integrated wireless chip. BLE connection to smartphones can be established from version 4.1.

Profile

Proprietary

No standard BLE profile is used.

Wireless Range

≥ 5.0 m

Depends on environmental conditions and the presence of other active
2.4 GHz wireless devices.

Bandwidth

54 kB/s

Typical data transmission bandwidth.

Transmission Speed

~ 19 s/MB

Equals approx. 04:27 min. transmission time for complete memory transmission.
