They are usually small and extremely practical: wearables. Small computer systems worn on the body that measure blood pressure, calorie consumption or sleep quality. The functional diversity of wearables makes them helpful, practical companions in everyday life. Fitness trackers or smartwatches are mostly worn on the wrist and must be small and lightweight.

Wearable technology – we are also in wearables

Therefore, the size is decisive for built-in crystals and oscillators. We manufacture ever smaller hardware components for our customers. In addition, these must be robust and insensitive. After all, wearables should also work reliably when training in the gym or when downhill biking off-road.

Our “clocks” are in these wearables:

  • Fitness Tracker
  • Activity Tracker / Sleep Tracker
  • Smart Watches
  • Health Tracker
  • Smart clothing
  • Headphones
  • Data glasses

Application examples from practice

Tracking for intelligent bike trainer with terrain simulation and individual rider setting

  • Quartz for optimized circuit design
  • Low power consumption
  • Precise function over the entire temperature range

  • GEYER KX-327RT series tuning fork crystal (2.0 | 1.2 | 0.6 mm): 32.768 kHz/7 pF for optimized circuit transient response and low power consumption

  • Quartz crystal from the GEYER KX-5T series (2.0 | 1.6 | 0.45 mm): 32.0 MHz/8 pF for stable circuit design due to low load capacitance

  • Tight tolerances over the extended temperature range

Fitness bracelet with pedometer and Bluetooth connection

  • Accuracy due to Bluetooth interface
  • Small size

  • Shock and vibration resistance
  • Low power consumption
  • Temperature compensated crystal oscillator (TCXO) with 0.5 ppm tolerance over the temperature range
