IMSES / Intelligent Multi-Sensor Elbow Sleeve

Elbow Sleeve
Live Monitor

Five sensors and a motor actuator stream over BLE. Connect your device or click Demo Mode on each tab to explore the interface.

Heart Rate

--BPM

Computed from MAX30102.

SpO2

--%

Computed oxygen saturation.

Temperature

--C

Estimated from NTC.

Current Angle

--DEG

Mapped from flex raw data.

Bend Speed

--DEG/S

Closing speed used for protection trigger.

Motor Guard

IDLESTATE

Forward, settle, reverse cycle status.

Guard Timer

0.0S

Time left in the active motor phase.

Guard Count

0RUNS

Protection cycles since boot.

Angular Accel

--DEG/S2

Second derivative of angle.

Flex Raw

--ADC

Flex sensor raw ADC.

EMG Raw

--ADC

EMG sensor raw ADC.

MAX IR

--RAW

IR photoplethysmography → used to compute SpO₂ and heart rate.

MAX Red

--RAW

Red LED absorption → combined with IR via Beer–Lambert law for SpO₂.
