To minimize the power line interference (50 Hz/60 Hz) and improve the quality of the output signal, it is recommended to use the BLE link.
4.1 PHOTOPLETHYSMOGRAPHY (PPG) - ADPD4100
The ADPD4100 operates as a complete multimodal sensor front end, stimulating up to eight LEDs (four on the VSM Watch) and measuring the return signal on up to eight separate current inputs. Twelve time slots are available, enabling 12 separate measurements per sampling period.
The data output and functional configuration utilize an I2C interface on the ADPD4001 or a serial port interface (SPI) on the ADPD4000. The control circuitry includes flexible LED signaling and synchronous detection. The devices use a 1.8 V analog core and 1.8 V/3.3 V compatible digital input/output (I/O).
Refer to the ADPD4100 product page and data sheet for further details.
Details regarding the hardware implementation are found in Table 3 and Table 4.

4.2 MOTION AND ACTIVITY - ADXL362
Motion is sensed by the ADXL362, an ultra-low power, 3-axis, ±2 g/±4 g/±8 g digital output high resolution (1 mg/LSB) accelerometer. Its power consumption is 1.8 µA at 100 samples per second (SPS) and 3.0 µA at 400 SPS, while its motion activated wake-up mode only requires 270 nA.
A pedometer algorithm is embedded for evaluation that can be enabled in Wavetool.
Check ADXL362 datasheet for more details on various configuration options available for this part https://www.analog.com/media/en/technical-documentation/data-sheets/ADXL362.pdf.
4.3 ELECTROCARDIOGRAPHY - AD8233
The AD8233 is a 50 µA 2.0 mm × 1.7 mm WLCSP low noise single lead analog output biopotential front end.
Integrated ECG Electrodes
The AD8233 is connected to the electrodes hosted in the top and bottom surfaces of the watch. The two electrodes on the top of the watch are connected to IN− pin and RLD pin, while the two electrodes on the bottom of the watch are shorted together (temporarily while this measurement is active) and connected to the IN+ input.
The quality of the contact of the bottom electrodes has a dramatic effect on the output waveform. Dry, hairy skin poses a challenge for this measurement until moisture accumulates between the skin and the electrodes. This usually happens a few minutes after the user puts on the device. Accumulated moisture decreases the contact impedance and, therefore, the quality of the output waveform improves.
The configuration of this signal chain is like an ambulatory ECG device (Holter monitor).

External ECG Cables
The charging cradle provides a secondary micro-USB connection to be used with external wired electrodes.
Impedance is measured using the AD5940 Impedance AFE. Proper electrical contact between these two electrodes and the skin is critical for accurate and reliable long-term measurement. Adequate tightness of the watch strap helps achieve a proper contact and wearing the watch beside (but not on top of) the lunar styloid process (the protruding wrist bone) also helps ensure a reliable and high-quality measurement.
Note that these two electrodes are also used by the ECG measurement, which temporarily shorts them together. Therefore, the impedance measurement is not valid while the ECG measurement is ongoing.

The skin temperature measurement is based on a thermistor (NTCG104EF104FTDSX). The thermistor used in the skin temperature measurement is thermally coupled to the bottom of the watch. This thermistor is connected to one of the analog inputs of the ADPD4100 and its performance is heavily dependent on the mechanical connection that is made to the body. Being said that this version of watch has a poor heat conduction between the thermistor and watch body which results is larger inaccuracy in the temperature data then theoretical value of 0.2⁰C. To overcome this shortcoming user is allowed to configure a temperature correction factor using Analog WaveTool depending on the temperature deviation seen in their device. The procedure to configure the correction factor is explained in detail in the getting started guide.

Basic modes of operation have been designed for the VSM Watch that are selectable by supplied Device Configuration Files:
- High Performance PPG
- Synchronized PGG with EDA
- Synchronized PPG with ECG spot-check
- High Performance ECG spot-check
- Multi-wavelength PPG
- Future Use Cases will continue to be developed.
These modes of operation are intended to demonstrate the different types of configurations that are possible with the VSM Watch but are not specific to an end-application. The high configurability of the VSM Watch allows for the possibility to program a configuration that cannot be supported by the existing hardware, software, and firmware. Users can load these Use Cases as a known-good starting to point to explore measurements of interest before modifying the platform for their specific purpose.
Please refer to the Software User Guide for details on how to evaluate and modify these Use Cases in Wavetool.

Basic algorithms are included with the VSM Watch to demonstrate this type of functionality. More advanced algorithms with specific device configurations are provided here.
PEDOMETER
A pedometer algorithm takes raw data from the 3-axis accelerometer and outputs the steps taken.
AUTOMATIC GAIN CONTROL
The digitized output of the ADPD4100 is fed to this algorithm to ensure that the LED current and AFE gain is configured appropriately to maximize the usefulness of the Optical Signal. The default target is 70% of the allowable range for each LED (independently determined). This Gain Control is not optimized to achieve an ideal performance versus power. Further improvements can be made based on the end application’s requirements to achieve a better battery life.
HEART RATE MONITORING
This algorithm measures heart rate using PPG/ADPD signal while removing the motion-based interference. It operates on a single channel PPG/ADPD signal, together with 3-axis accelerometer data to produce the heart rate. The algorithm is provided as a pre-built Cortex-M4 library along with header file. It is designed to work with PPG and accelerometer data at 50Hz.
SIGNAL QUALITY INDEX
PPG signals collected via wearable devices are prone to noise sources and other artefacts that negatively impact the measurement accuracy of the sensor. The Signal Quality Index (SQI) algorithm gives a score (index) for each time window/segment of PPG data to determine if it is of a sufficiently high quality to be useful for other vital sign extraction or clinical diagnostic algorithms estimate of the heart rate. The SQI feature is supported for PPG signal frequencies ranging from 25-100Hz. The SQI score is a floating-point value between 0(poor signal quality) and 1(excellent quality). The Wavetool has option to display the SQI in all use-case views. The SQI can be calculated on any of the Green, Red, IR or Blue LEDs present on watch.
ECG HEART RATE MONITORING
This algorithm measures heart rate from the ECG signal by detecting the QRS peak of the ECG signal. The algorithm is provided as a pre-built Cortex-M4 library along with header file. It is designed to work with ECG signal with ODR up to 200Hz.
BATTERY LIFE
The battery life is determined by the type and number of sensors enabled, the sampling rate configured and is also dependent on other configuration details such as the LED current in the photoplethysmography measurements.
Table 10. System Battery Life for Several Use Cases
| Use Case | Memory | Live BLE | Battery Life (Hours) |
|---|---|---|---|
| Shipment Mode | No | No | 30000+ |
| Hibernate | No | No | 1000+ |
| PPG – High Performance | Yes | Yes | 14 |
| ECG – High Performance | Yes | Yes | 40 |
| PPG + Impedance | Yes | Yes | 50 |
| PPG + ECG | Yes | Yes | 40 |
| PPG – All LEDs | Yes | Yes | 20 |
The VSM watch is powered by a rechargeable 200 mAh battery.
Note: All the default use cases are designed to maximize the performance. By modifying various parameters of the AFEs one can achieve longer battery duration. For instance, in ADPD4100, the default gain in AGC algorithm is set to 25K, to get best PPG performance with various skin tones. Setting the gain to 100k/200k and lowering current value will result in significant improvement in battery duration for continuous usage.
MEMORY FOOTPRINT
The watch hosts a 512 MB memory.
The actual capacity of the memory is determined by the type and number of sensors enabled and the sampling rate configured.
