Wireless Implant
Wirless ECG for mice or rats

BIOPAC Epoch Wireless ECG Transmitters

The single-channel implantable wireless ECG transmitter amplifies and transmits high-fidelity ECG data to an EPOCH ECG System for long-term wireless ECG recording from mice or rats in their home cages.

BIOPAC Epoch Wireless ECG Transmitters

Part #: EPOCH-M-ECG-SEN, EPOCH-R-ECG-SEN

The single-channel implantable wireless ECG transmitter amplifies and transmits high-fidelity ECG data to an EPOCH ECG System for long-term wireless ECG recording from mice or rats in their home cages. Implant contains a small amplifier, transmitter, and a battery (mouse: 2-mo. battery; rat: 6-mo. battery) encapsulated in medical-grade epoxy. Each electrode is 7-strand braided stainless steel with Teflon insulation. Each strand is 50 μm in diameter, making the bare electrode 152 μm in diameter (229 μm diameter insulated). There are two electrode leads on the ECG transmitter.

Single-Channel ECG Transmitter Implant

  • Footprint: 8 mm x 9 mm (2 month), 8 mm x 12 mm (6 month)
  • Weight: 2.3 g (2 month), 4.0 g (6 month)
  • Volume: 0.756 cm3 (2 month), 1.344 cm3 (6 month)
  • System Gain: 2000x; ±1.0 mV range, 1.0 mV in = 2 V out
  • Bandwidth: 0.1-200 Hz per channel
  • Input Referred Noise: < 8 μV rms at 100 Hz (11 μV rms at 200 Hz)

Sensors available activated or deactivated

  • Sensors will be shipped with the battery running unless requested as “deactivated” when ordered.
  • Request “deactivated sensors” in the comments section when ordering sensors or systems online.
  • Deactivated transmitters must be activated within 6 months of shipment to ensure the full 2-month or 6-month active battery-life.
  • Requests for deactivated sensors require that the user has an EPOCH-ACTI on-hand or includes one in the EPOCH order.
  • Add the Sensor Activation & Test Utility (EPOCH-ACTI) to start a deactivated sensor battery when ready to use the transmitter.
  • The reusable activator is battery operated and can be used for any sensors that are ordered as deactivated.
  • The activator utility can also output two independent channels of data (sinewaves) for testing purposes.
