Abstract
The present disclosure relates to systems and methods for low-power, data transmission using ultrasound signals. In one implementation, a data transmission system includes an ultrasound transducer configured to generate ultrasound signals in response to power supplied from a power source, and a mechanical ultrasound amplifier coupled to the ultrasound transducer, the ultrasound amplifier having a substrate adapted to function as a soundboard to amplify the ultrasound signals. The range of the data transmission system may be increased with a relay system. The relay system may include one or more detectors and one or more repeaters.

A data transmission system, comprising:
- an ultrasound transducer configured to generate ultrasound signals in response to power supplied from a power source;
- and
- a mechanical ultrasound amplifier coupled to the ultrasound transducer, the ultrasound amplifier comprising a substrate adapted to function as a soundboard to amplify the ultrasound signals.
A data transmission system for use in a personal hygiene product, comprising:
- a moisture sensor coupled to the personal hygiene product;
- an ultrasound transducer configured to generate ultrasound signals in response to power supplied from a power source;
- and
- a mechanical ultrasound amplifier coupled to the ultrasound transducer, the ultrasound amplifier comprising a substrate adapted to function as a soundboard to amplify the ultrasound signals.
A data transmission method, comprising:
- applying power from a power source to an ultrasound transducer, the ultrasound transducer physically coupled to a substrate and electrically coupled to the power source, the substrate adapted to function as a soundboard to amplify ultrasound signals generated by the ultrasound transducer;
- in response to the ultrasound transducer receiving the power from the power source, generating ultrasound signals with the ultrasound transducer;
- and
- amplifying the ultrasound signals using the substrate, the substrate functioning as a soundboard for the ultrasound transducer.
