An HEMT includes an aluminum gallium nitride layer. A gallium nitride layer is disposed below the aluminum gallium nitride layer. A zinc oxide layer is disposed under the gallium nitride layer. A source electrode and a drain electrode are disposed on the aluminum gallium nitride layer. A gate electrode is disposed on the aluminum gallium nitride layer and between the drain electrode and the source electrode.

High electron mobility transistor

The present invention provides a wearable device for monitoring blood-pressure.

Blood pressure measurement devices and methods

A semiconductor device includes an epitaxial substrate. The epitaxial substrate includes a substrate. A strain relaxed layer covers and contacts the substrate. A III-V compound stacked layer covers and contacts the strain relaxed layer. The III-V compound stacked layer is a multilayer epitaxial structure formed by aluminum nitride, aluminum gallium nitride or a combination of aluminum nitride and aluminum gallium nitride.

Semiconductor device with strain relaxed layer

A high electron mobility transistor (HEMT) includes a buffer layer on a substrate, in which the buffer layer includes a first buffer layer and a second buffer layer. Preferably, the first buffer layer includes a first layer of the first buffer layer comprising AlGaN on the substrate and a second layer of the first buffer layer comprising AlGaN on the first layer of the first buffer layer. The second buffer layer includes a first layer of the second buffer layer comprising AlGaN on the first buffer layer and a second layer of the second buffer layer comprising AlGaN on the first layer of the second buffer layer, in which x&#x3e;z&#x3e;y&#x3e;w.

Devices and methods for monitoring blood pressure with a wearable device, which includes a contact member that concentrates radially directed tissue movement produced by arterial motion into a relatively small spot to compress the strain device. This concentration significantly increases the sensitivity of the force detecting device and allows further miniaturization of the device.

A door includes a door panel and an electric lock device including a solar energy module, a biometric verification module, a control module and an electric lock. The solar energy module converts solar energy into an electricity output. The biometric verification module receives a biometric input signal relative to a biometric feature, determines whether the biometric feature conforms with a set of pre-established data, and generates a conforming signal if the determination is affirmative. The control module receives the conforming signal to generate a control signal and an unlocking signal. The electric lock receives the control signal and the unlocking signal. The electric lock operates to unlock the door panel.
