Application Areas

Bluetooth LED body fat scales, body composition analyzers, body fat scales, etc.

Weighing & body impedance

A single IC with greatly reduced numbers of resistors, capacitors etc to implement weighing and body impedance measurement.

Bluetooth integration scheme

Contains a fully integrated Bluetooth IC as well as a wide choice of other integrated interfaces to offer flexible connection to external smart devices.


Holtek has released a dedicated MCU for body fat scale applications. which contains a fully integrated 24-bit Delta Sigma A/D converter and an AC body fat measurement circuit. This device can accommodate both four and eight electrode application types making it suitable for Bluetooth body fat scales as well as other applications that requiring body impedance measurements.
As the health instrument market continues to mature, body composition and body fat scale measurement functions are becoming more widespread. Currently, these smart devices are often used in conjunction with smart phones. Holtek has provided a solution which has integrated body fat measurement, body weight measurement and Bluetooth-to-internet functions in one device. This high level of functional integration will offer great advantages for the design and volume manufacture of related products.
