Getting closer. Dr. Oschmann responded to an email query with a lead to The Institute of HeartMath. He recommended this article, The Electricity of Touch (available as a PDF download). Their main accomplishment? "This study represents one of the first successful attempts to directly measure an energy exchange between people."
I also found this press release, which states: "The Institute of HeartMath (IHM) in Boulder Creek, California is a nonprofit research organization that has been studying emotions and the electromagnetic energy generated by emotions and the bodyóspecifically the heartófor over a decade. A recent study conducted by IHM represents one of the first successful attempts to directly measure an energy exchange between people, and provides a testable theory to help explain why we can sense what other people are feeling and why we tend to know when someone is behind us without hearing or seeing them."
