Nancy Dougherty, an engineer at Proteus Biomedical, made her own set of "mindfulness pills" with embedded sensors that transmits signals to her phone, recording each time she took a different pill. By playing with technology and the placebo effect, she has found a way to manage her mood through mindfulness and quantified feedback via her phone. For example, she found that taking the "energy" pill actually made her bike harder, and a "focus" pill made her do more work. As a result, she found she didn't need to use the "calm" or "happy" pills. Watch this fascinating video for more details.
