ABSTRACT:
An electronic soap bubble sensing and responsive device which is activated upon making contact between a soap bubble and an electronic sensor. The device consists of two electrodes mounted on a support frame and electrically coupled to internal electrical signal generation circuitry. The soap bubble sensor includes electrodes which are positioned so as to contact the soap bubble conjointly. Soap bubble fluid being conductive allows such contact to complete a trigger circuit, which contact also bursts the bubble, thereby breaking the circuit. The electrodes have a geometric configuration so as to maximum the conjoint contact with spherical bubbles, and the electrodes are supported on a frame so as to minimize wetting of the frame and triggering inadvertent activation. The completed electrical circuit can activate any sensory output as a result of the triggering, including sounds, lights or motion. Other sensors disclosed for discerning the presence of a soap bubble include impedance change of an antenna wire, optical sensing, magnetic sensing, and capacitive sensing.
