Piezo drivers are amplifier-type power supply,For the stable driving of the amount of displacement and the degree of vibration for each piezo element dependent on its purpose Piezo elements resemble capacitive components in their features.
The piezo driver is ideal for driving piezo transducers with high capacitance and high frequencies. Piezoelectric actuators and transducers are very capacitive electronics.
At higher frequencies, their total impedance is quite low due to their high capacitance. Additionally, 20Vpp to 60Vpp or higher high voltage is frequently needed for these piezo devices.
A high-current piezo driver is necessary because to the high frequency and high voltage combination. The connection and configuration of the high-frequency, high-current piezoelectric driver.
Instead of a standard programmable DC power supply, they need an amplifier type power supply that can discharge and maintain the output power supply to provide the best drive.
Additionally, when operated at a quick response rate, greater output current is needed in addition to responsiveness. Choosing a power supply that is appropriate for the element being utilised as well as the usage circumstances is the first step in selecting a piezo driver.
With pulse driving with an actuator, ringing tends to occur in the output waveform, and in some cases abnormal oscillation may occur. Degradation and breakage of the piezo element occurs in such cases.
The Global Piezo drivers market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The BOS1921, a compact piezo driver from Boréas Technologies, frees PC OEMs from the specific circuits that other piezo drivers need for force sensing and provides autonomous operation and sensing for piezo haptic trackpads.
This improvement over the BOS1901, Boréas’ first-generation piezo haptic driver, lowers bill of materials (BOM) costs by up to 2x, maintains the thinness of piezo haptic trackpads, enhances responsiveness, and offers 15x higher sensing resolution.
PC OEMs are in a highly competitive market with tight margins—and piezo haptic trackpads have become a crucial difference.
Piezo haptic trackpads are popular designs for laptops and notebooks because they are thinner and lighter than traditional mechanical trackpads and support for crisper, cleaner tactile sensations. Piezo haptic drivers, such as the BOS1921, are driving this migration.
