Timing Devices (MEMS Resonator / Crystal Unit / Ceramic Resonator)MEMS Resonators and Crystal Units for Small Wearable Devices

Current State of Compact Wearable Devices

As the Internet of Things (IoT), in which all sorts of products are connected to the internet, becomes more widespread the requirement for compact designs becomes increasingly prevalent.

This is especially true for small wearable and healthcare devices to be smaller and lighter to realize attractive designs and comfortable use for long periods of time.

Furthermore, such devices can utilize short-range wireless communication (Bluetooth® Low Energy, Zigbee®, NFC, etc.) to enable an exchange of information between various devices or remote operation and controls of devices.

Murata MEMS resonators and crystal units are ideal for providing value in such applications.

Requirements of compact wearable devices

As compact wearable devices attain more advanced functionality, the number of components they contain increases while at the same time they must be smaller, lighter, and able to operate for extended periods of time.

However, it is difficult to develp products which are more compact and lightweight while also achieving extended battery operation time.

Solutions for compact wearable devices

Murata’s crystal units and MEMS resonators are the perfect solution to this problem.
