Patent number: 11114955Abstract: Devices and methods relate to a portable self-powered wireless sensor and transmitter providing a tactile driven electric generator, using a 3D printed nano carbon and polymer electrodes. The device has two electrodes capable of producing greater than 2000 V, which when connected to a metal conductor is sufficient to create an electric field that can be used to wirelessly communicate a signal over a range of a few tens of meters. The sensor is completely self-powered and requires no motors or additional power such as active power supplies, batteries, or capacitors. The sensor generated waveform can be modulated by mechanical action such as hand tapping in a given sequence, which is preserved in the wireless signal (akin to Morse coding) and can be detected by existing compatible commercial electronic receivers. Resulting devices are suitable for security applications requiring wireless transmission of codes.Type: GrantFiled: November 16, 2018Date of Patent: September 7, 2021Assignee: Clemson UniversityInventors: Sai Sunil Kumar Mallineni, Herbert W.
