# Mindfield Biosystems Ltd.

> Mindfield Biosystems is a German manufacturer of biofeedback and neurofeedback devices, mobile sensors, and software. Founded in 2003, Mindfield offers a complete ecosystem from smartphone-based sensors (eSense) to professional multi-channel amplifiers (MindMaster) and an open visual biofeedback design platform (BioEra). Products are CE-certified and used by therapists, researchers, and home users worldwide. 14 peer-reviewed studies validate Mindfield products in clinical and research settings.

Mindfield Biosystems Ltd. is based in Berlin, Germany. The company was founded by Niko Rockensuess, a biologist specializing in neurobiology (Diplom-Biologe, Neurobiologie). Mindfield serves therapists, clinics, researchers, and individuals seeking biofeedback and neurofeedback solutions for stress management, performance optimization, and therapeutic applications.

Key differentiator: Mindfield is the only manufacturer offering the complete biofeedback and neurofeedback ecosystem -- from affordable mobile Bluetooth sensors for home use (eSense series) through professional multi-modal biofeedback systems (MindMaster BioNeuro) to professional EEG neurofeedback (MindMaster Neuro, up to 6-channel EEG) and an open software platform (BioEra).
