t-Lead: Tripolar Concentric Ring Electrode (TCRE)-based sensor
- Each TCRE sensor consists of three electrode elements: the outer ring, the middle ring, and the center disc.
- The outer ring of the TCRE emulates disc electrode biopotentials (eEEG).
- Suitable for acquiring EEG in applications such as event related potentials (ERP), brain-computer interface (BCI) and seizure detection. Can also be used to acquire electrocardiography (ECG), electromyography (EMG), and other biopotentials.
- Use with conductive paste.
- Work in conjunction with the t-Interface.
- Patent No. US8352012B2, US8615283B2, US8626259B2, and US9399133B2

t-Interface
- The t-Interface serves to configure the TCRE electrode elements, route, and pre-amplify the signals.
- Signals recorded with disc electrodes are known to be prone to artifacts. Incorporating the t-Leads and t-Interface into your current amplifier system improves the artifact rejection of your system, allowing for higher-fidelity biopotential signal acquisition and typically shorter acquisition times.
- The t-Interface has been designed to be compatible with your current amplifier and software. Its outputs have standard touch-proof connectors that mate with common EEG amplifier head boxes (Biologic, BioPac, Brain Vision, Brain Products, EB Neuro, Grass/Natus, g.tec, Nihon Kohden, Neuroscan, TDT amplifiers, etc.).
