What Types of Piezoelectric Materials Does TRS Technologies Offer?

Updated

TRS Technologies supplies five categories of piezoelectric and electrostrictive materials: high-performance piezoelectric single crystals, soft piezoelectric ceramics, hard piezoelectric ceramics, high-temperature piezoelectric ceramics, and electrostrictive ceramics. The right choice depends on whether your application prioritizes sensitivity, power handling, temperature range, or a non-hysteretic strain response. TRS positions itself as a custom-solution supplier rather than a catalog parts vendor, so material selection is typically made in collaboration with the company for a specific application.

Material categories and what each is for

Material type Primary characteristic Typical fit
High-performance piezoelectric single crystal High sensitivity Applications needing maximum strain or coupling from a small signal
High-sensitivity soft piezoelectric ceramics High sensitivity Sensing and low-drive actuation where output per unit input matters
High-power hard piezoelectric ceramics High power Drive and actuation under high electrical or mechanical load
High-temperature piezoelectric ceramics Operation at elevated temperature Environments where standard ceramics would depolarize or degrade
Electrostrictive ceramics Electrostrictive (non-piezoelectric) response Applications needing strain without the hysteresis of a piezoelectric response

The distinction between soft and hard ceramics is the most common decision point. Soft ceramics trade higher sensitivity for lower power capability; hard ceramics trade some sensitivity for the ability to handle high drive levels without excessive heating or depoling.

How to choose among them

Work from the constraint that is hardest to change:

  • Signal level is the limit — if you need the largest possible response from a limited drive voltage, start with single crystal or soft ceramics.
  • Drive level is the limit — if the element must survive high electric fields or high mechanical stress, hard ceramics are the appropriate family.
  • Temperature is the limit — if the operating temperature exceeds what standard ceramics tolerate, the high-temperature line is the relevant one.
  • Hysteresis is the limit — if repeatable, low-hysteresis strain matters more than raw piezoelectric coupling, electrostrictive ceramics are the alternative.

These are not strict either/or choices. TRS describes its business as collaborating with customers on custom piezoelectric components, so a material can be tailored to the application rather than selected off a fixed list.

What TRS also provides around the material

Beyond the material itself, the site lists custom piezoelectric components with quick delivery, engineering services, and a quality system for piezoelectric powder, ceramic, and crystal production that is ISO 9001 registered. For buyers, the practical implication is that material selection and component fabrication can be handled together rather than sourced separately.

Getting a specific answer

Because the material choice depends on your application's drive level, temperature, and sensitivity requirements, the site routes this through a quote request rather than a published selection chart. Contact details and a request-quote path are provided on the site, and the company's stated model is to work directly with you on a high-performance custom solution. If you already know your operating conditions, that information is what determines which of the five material families applies.
