Retinal prostheses for blindness due to retinal photoreceptor degeneration stimulate the retina electrically to evoke a pseudolight sensation (phosphenes). Although rectangular pulses of electri ... Read More

In this work, we developed a surface-acoustic-wave (SAW)-based immunosensor for the monitoring of house dust mite (HDM) allergen, Dermatophagoides farinae group 2 (Der f 2). The SAW immunosensor ... Read More

Implanted electrodes are widely used for in vitro and in vivo neural recording; however, the established properties of these electrodes can change over time. Here, we characterize the long-term c ... Read More

Monitoring blood lactate concentration is important in clinical diagnosis and evaluation of fitness care. Electrochemical enzyme sensors are commonly used for the measurement of lactate owing to ... Read More

A flexible temperature microsensor based on a polyimide thin-film substrate is presented. The polyimide thin-film substrate can achieve good contact with skin during tumor ablation, and it has a ... Read More

In this work, a bridge-type piezoelectric energy harvester combined with proof masses that can work at high acceleration was designed, simulated, and fabricated. The energy harvester was achieve ... Read More

With the development of low-power-consumption electronic devices and systems, the development of power supplies will be a major challenge. High-performance piezoelectric energy harvesters (PEHs) ... Read More

Fecal impaction is a gastrointestinal problem that occurs in all age groups. Traditional therapy with drugs or surgery may result in serious complications for patients. Softening hard stool in ... Read More
