Product comparison
Aidlab 2 vs Shimmer3R ECG
Shimmer3R ECG is a configurable five-wire, four-lead acquisition unit with gain, sample-rate, respiration-mode, and microSD controls. Aidlab 2 is a compact strap-mounted system combining 1-lead ECG with chest respiration, EDA, temperature, motion, and GNSS.
COMPARED MODEL
Shimmer3R ECG
Configurable ECG acquisition unit with five wired leads
- Five-wire, four-lead ECG with software-configurable gain from 1 to 12 [4]
- Software-configurable data rates from 125 to 8000 samples per second [4]
- Integrated 8 GB microSD logging and respiration demodulation with a documented ECG interference caveat [4][5]
EDITORIAL INTERPRETATION
The 30-second verdict
This decision guide is Aidlab's interpretation of the documented capabilities below, not a controlled head-to-head result.
CHOOSE AIDLAB 2 IF
- Repeated participant setup should use one compact module and electrode strap.
- ECG, chest respiration, EDA, temperature, motion, and GNSS belong in one device plan.
- A curated cross-platform SDK is preferable to extensive acquisition controls.
CHOOSE SHIMMER3R ECG IF
- Four ECG leads, configurable gain, and selectable acquisition rates are required.
- Wired electrodes and a modular lab workflow are acceptable.
- Raw microSD logging and ConsensysPRO or instrument-level control fit the protocol.
DECISION BOUNDARY
Shimmer3R ECG documents configurable leads, gain, and acquisition rates. Aidlab 2 packages a fixed 1-lead setup with additional published modalities. Neither design establishes better signal quality by itself.
DOCUMENTED CAPABILITIES
Lead setup, acquisition controls, and local logging
The comparison separates electrode configuration from sensor breadth and software workflow. Published sample rates alone do not establish accuracy.
| Criterion | Aidlab 2 | Shimmer3R ECG | Editorial interpretation |
|---|---|---|---|
| ECG setup | 1-lead ECG through a reusable chest module and electrode strap | Five-wire, four-lead ECG setup with configurable gain and data rate | |
| Respiration | Dedicated chest-movement waveform and respiration rate | Impedance-pneumography respiration demodulation; Shimmer notes interference on all ECG channels when this mode is enabled | |
| Additional sensing | EDA, skin temperature, 9-axis motion, microphone, and GNSS in the same product | 10-DoF inertial sensing; GSR and other modalities use other Shimmer units | |
| Local recording | Internal storage with later synchronization through Aidlab SDK | Raw logging to an integrated microSD card | |
| Research control | Curated signal set and cross-platform application SDK | Software-configurable gain and sampling rates plus APIs and instrument drivers | |
| Best fit | Remote and field research, custom health apps, biofeedback, and one-module strap workflows | Bench validation, electrophysiology, configurable ECG/EMG, and modular lab systems |

Shimmer documents configurable ECG acquisition up to 8000 SPS. Aidlab 2 sampling rates are not asserted here because its product page does not provide a model-specific rate table.
SETUP AND CONTROL SURFACE
What the protocol asks the operator to configure
A five-wire acquisition unit and a strap-mounted multisensor system create different setup, configuration, and logging responsibilities.
Participant setup
Aidlab 2
Attach one reusable module to an electrode chest strap.
Shimmer3R ECG
Place five wired electrodes for four leads and attach the ECG unit.
The documented setups are one module and strap versus five wires and four leads.
Acquisition controls
Aidlab 2
Use a curated 1-lead ECG and published multimodal sensor set through Aidlab software interfaces.
Shimmer3R ECG
Configure amplifier gain, data rate, lead behavior, and supported respiration mode.
Configuration depth is valuable when the protocol needs it and overhead when it does not.
Local and live data
Aidlab 2
Plan around published internal storage, Bluetooth/Wi-Fi capabilities, and Aidlab SDK access.
Shimmer3R ECG
Stream through ConsensysPRO or log raw data to the integrated microSD card.
Both support untethered collection, through materially different operator workflows.
QUESTIONS BUYERS ASK
Frequently asked questions
Shimmer3R ECG. Shimmer is a modular family, so the GSR+, IMU, EMG, and Verisense products should not be treated as if they were one device.
Shimmer3R ECG. It is specified as a five-wire, four-lead system. Aidlab 2 uses a simpler 1-lead chest ECG setup.
Aidlab 2 uses one chest module and electrode strap. Shimmer3R ECG uses five wires and four leads and exposes configurable gain and acquisition rates. Choose the setup and controls required by the protocol.
