Use of electric field sensors for recording respiration, heart rate, and stereotyped motor behaviors in the rodent home cage.

•A novel method to continuously monitor animal physiology and behavior is proposed.•Plessey EPIC sensors offer a cheap, noninvasive alternative to traditional methods.•Sensors accurately detect respiratory and heart rate when appropriately positioned.•Sensors detect stereotyped rodent behavior and activity in a home cage environment.•Widespread applicability for high-throughput home cage studies is envisioned.
