In March 2019, Alps Alpine developed and began production of the HSFPAR004A force sensor. This sensor fits inside the tip of a tablet stylus and enables precise reproduction of stroke thickness, corresponding to the pressure applied to the stylus tip. With high sensitivity, high resolution, high linearity, and excellent impact resistance, the HSFPAR004A force sensor has been well-received by many customers.
 
Now, Alps Alpine has developed the HSFPAR007A force sensor, which has a footprint only 40% that of the HSFPAR004A while retaining the core performance capabilities of its predecessor. The new product is small enough to fit inside the thinnest styluses used with smartphones. This enhances design flexibility for device manufacturers and helps improve the usability of smartphone drawing applications, for example.
 
The HSFPAR007A force sensor detects forces as light as 0.01 N, enabling applications in robotic arms and other industrial equipment that handles precision devices. The product has a wide range of potential uses as a sensor for detecting force along the Z-axis. For example, it can be embedded beneath a touch panel or capacitive sensor to detect the force applied to the operating surface, and even determine whether an input operation was intentional or accidental.
