A portable, low-cost, all-in-one biopotential monitoring system that can be used for demonstrating the basic characteristics of electrical activities of the human brain and body for undergraduate physics students is described. The monitoring system consists of a wireless biopotential amplifier, an electrode cap and a software interface. Some of the biopotential activities recorded from the monitoring system, together with theoretical explanations associated with them are presented. Experimentation with the system will provide students with an opportunity to verify the theories involved in biopotential activities. The construction of the system can also be an interesting project for undergraduate students and it exposes them to instrument construction and troubleshooting techniques.
