Recently, electret-based electrostatic and triboelectric energy harvesting devices have demonstrated their great potential in converting ambient mechanical energy to electrical energy due to their merits of low cost, easy formation and long-term stability. For electret-based generators, the performance of the state-of-the-art MEMS energy harvesters mostly falls into the range of nW or μW level, limiting...
Atmospheric-pressure plasma jet (APPJ) has attracted tremendous attention in the past decade mainly due to its low cost and flexibility without the use of expensive vacuum equipment. It has found numerous applications such as surface cleaning, surface modification, thin-film deposition and recently biomedical applications that may include sterilization, blood coagulation, cell growth enhancement and...
HP has recently made its plans to develop an ultrahigh-resolution seismic sensing solution public. This solution is being developed with Royal Dutch Shell Corporation for oil and gas exploration. Central to delivering this system is HP's new single axis seismic grade MEMS accelerometer. The HP device uses both bulk micromachining methods and standard thin film technologies as well as HP's new three...
Electrical stimulation of the optic nerve with penetrating electrode array for visual recovery had been proposed by C-Sight group. This paper presents the latest progress of various component parts of visual prosthesis, including design and testing of neural stimulator, fabrication of multi-channel flexible microelectrode array. According to the experiment data, the linearity between practical stimulator...
A novel scalable and stackable nonvolatile memory technology suitable for building fast and dense memory devices is discussed. The memory cell is built by layering a storage element and a selector. The storage element is a Phase Change Memory (PCM) cell and the selector is an Ovonic Threshold Switch (OTS). The vertically integrated memory cell of one PCM and one OTS (PCMS) is embedded in a true cross...
The area of 'laboratory-on-a-chip', miniaturised or microfluidic analysis systems, is a rapidly developing field. At the microscale, electrokinetic processes become enhanced, and the advent of AC electrokinetics (EK) in recent years further promotes the development of electrokinetic devices for microfluidics. ACEK has demonstrated to manipulate fluids and polarisable particles at low voltages without...
