ZEUSSS is a self-powered microphone that is thin, flexible, and has the ability to sense vibration (sound signals) and wirelessly transmit the sound signal to computers by analog backscatter. ZEUSSS takes advantage of Triboelectric Nanogenerator(TENG) to transform vibration to energy and wirelessly transmit sensor data for ubiquitous computing applications such as low-cost sensing of audio and vibration on everyday objects and...

Cheating has always been a problem for academic institutions, but the internet has increased access to a form of academic dishonesty known as contract cheating, or "homework for hire." When students purchase work online and submit it as their own, it cannot be detected by commonly-used plagiarism detection tools, and this troubling form of cheating seems to be increasing.

We present an approach to addressing contract cheating:...

FingerPing is a novel sensing technique that can recognize various fine-grained hand poses by analyzing acoustic resonance features. A surface-transducer mounted on a thumb ring injects acoustic chirps (20Hz to 6,000Hz) to the body. Four receivers distributed on the wrist and thumb collect the chirps. Different hand poses of the hand create distinct paths for the acoustic chirps to travel, creating unique frequency responses at...

Small electronic devices are numerous and ubiquitous. In this era of IoT (Internet of Things), we will use this devices as sensors indoors or outdoors. They can be embedded in furniture, cloths, or even implantable devices; they can also be attached on trees or placed in corn elds. Any cable attached to the device limits the agility of it, so not in all possible scenarios will the devices be plugged with electric cable. In so...

The small size of wearable devices limits the efficiency and scope of possible user interactions, as inputs are typically constrained to two dimensions: the touchscreen surface. We present SoundTrak, an active acoustic sensing technique that enables a user to interact with wearable devices in the surrounding 3D space by continuously tracking the finger position with high resolution. The user wears a ring with an embedded miniatur...

We present an acoustics-based method that utilizes the human body as a communication channel to propagate information across different devices. Through a set of experiments with eight participants, we demonstrate that acoustic signals under 20kHz can be propagated within or between human bodies or even between the human body and the environment. We can detect the existence of touch contact by simply matching the frequency resp...
