Based on the improvements of the fabrication technologies, the dimension of the device has decreased to tens of nanometer. This scale approaches to most bio-molecules, such as DNAs and proteins. Therefore, the nano-scale device has become an important connection between semiconductor technologies and biomedical applications. However, few of previous studies consider the feasibility to integrate standard...
A system-on-a-chip (SOC) with integrated drug reservoirs for drug delivery is proposed. Electrolysis is used to generate microbubbles, which are employed as a force to open the reservoirs and release the drug. Wireless components, including an on/off keying receiver, microcontrol unit, regulator, clock divider, and power-on reset, are integrated for remote drug activation. The proposed microchip is...
Cardiovascular disease remains the main cause of death, and great efforts are spent on the design of ECG body sensors these years. Essential components such as analog frontend and wireless transceivers have been integrated on a compact IC with micro-Watt power consumption. To provide timely warning against the fatal vascular signs, based on the Chaotic Phase Space Differential (CPSD) algorithm, on-sensor...
Recently, micro- and nano-technologies have enabled rapid progress in biomedical applications. Although in vitro analytical and diagnostic tools have been the focus of such technologies, in vivo therapeutic and sensing applications have received significant attention in the past few years. Novel implantable drug delivery devices, which can precisely control key therapy parameters, have the potential...
